Thank for this tutorial. I believe the log should have been introduced in line three of the solution. I believe someone doesn't need that long approach to comprehend the idea. Kudos bro
@@romeopadzinorima3264That's the easiest and quickest way. The one used in the video is complicated. I watched it all because i thought there were no logarithms involved until the end. All the hustle of dividing with 2^x is unnecessary
Depends on what you're supposed to be taught . There's a curriculum for a reason Except for some special reason you don't teach this in secondary school
This is goood but mosttimes why not use a shorter form of expression because many may not jave much timing on exams hall. I will send in my own rough work for cross checking please is been long i deal on mathematics. X= 0.46 approximately 0.5. 2^[x+1] - 3^(2x) = 0 I introduced the bracket to get a straight equation then multiply The equation becomes 2x+2-6x=0 Now collect like terms, moving +2 the other side turns -2 2x-6x=0-2 -4x=-2 Now divide by coefficient of x -4x/-4=-2/-4 -4 cancel out -4 X=-2/-4 2 can divide bith numerator and denominator. Negative cancels out negative X=1/2 X=0.5 If from the video x is 0.46 approximately 0.5.
You have to go through it the hard way before you do it the easy way. That way your brain capacity will increase, so will your understanding for maths. I personally think all students should be taught the hard way before the easy way.
Nice working but note, as a good mathematician always let your "=" (equal to sign) align. The working isnt neat. The sign should be on a straight line downwards. Thanks for sharing
If we were to use a calculator we would do something like this: Give 1 to x Then give 0.5 to x Then give 0.4 to x Then give 0.45 to x Then give 0.47 to x Then give 0.46 to x The first one can be made by mind, just use 5 times your calculator. Isnt it easier?
Это не имеет вообще никакого значения, а вообще видео довольно странное, не может быть, чтобы на российской олимпиаде была такое бредовое задание . Решается оно просто в лоб, без всяких ухищрений, что обычно бывает на олимпиадах
Unfortunately this Maths does not takes anywhere African institution are so backward I spent a lot of time studying this things now I’m a professional worker and realise it just a waste of time. We have to know only the basic, and move on to catch up with world progress now we have AI others they building a lot of revolutionary machines us African still stuck studying unnecessary things even bible we take it so serious. 😢

*ln[2^(x+1)] = ln(3^2x)*
*(x+1)ln2=2xln3*
*(2ln3-ln2)x=ln2*
*x=ln2/(2ln3-ln2)*
*=ln2/ln(9/2)*
Too long bro
Its actually way shorter @romeopadzinorima3264

The Love Of Mathematics!!❤
I enjoyed this tutorial 😊
Thank you for this, it is a part of solving machine codes, I'm a software programmer
Not true...how? I am a programmer too and i don't this you use exponents and logarithms
Use MATLAB
Am a s.3 student appreciating for the good work done .. thanks a lot may u continue with that spirit
Glad you found it helpful!
Thanks for teaching.
basic level exponential equation, good explanation
Mathematics teaches you problem solving skills.through mathematics,you will learn that however hard a problem is,there is a solution
Maybe you catch lotto everytime you attempt, if indeed math solve anything
Making a lot of sense, thanks for the lesson
Thank you for this great video, I just enjoyed exponential for the first time, it's such a pity our school teachers confuse rather than teach us
Thanks so much ❤️

Excellent
This is goood but mosttimes why not use a shorter form of expression because many may not jave much timing on exams hall. I will send in my own rough work for cross checking please is been long i deal on mathematics. X= 0.46 approximately 0.5.
2^[x+1] - 3^(2x) = 0
I introduced the bracket to get a straight equation then multiply
The equation becomes
2x+2-6x=0
Now collect like terms, moving +2 the other side turns -2
2x-6x=0-2
-4x=-2
Now divide by coefficient of x
-4x/-4=-2/-4
-4 cancel out -4
X=-2/-4
2 can divide bith numerator and denominator. Negative cancels out negative
X=1/2
X=0.5
If from the video x is 0.46 approximately 0.5.
Many irrelevant steps when you should just have introduced logs way too early. Nonetheless, however the long route, you reached your destination
Nice one broo
Once you moved the exponentials each side, taking the log gives a linear equation for x.
He don’t know maths
Yh
He doesn't noe maths
Simple questions no need to complicate
Thank you
I always love mathematics but...
Mathematics never love me back🤣
😂
😅😅😅😅😅😅
Nobody has taught me this kind of mathematics
Nice one
Thanks man we'll explained
Thank you for helping
Why complicate a very simple math?
l wonder
This is how they teach in Nigeria. And they wonder why students find it hard

@amaranextdoor it makes you understand every step of the way.
Solving from first principle even though not applicable in our political system

U could even take logs from beginning
Thank you for your tutorial but do we really need this long process?
Exactly my question
Does it put food on the table?
Can the equation pay any bills? 🙁
Why didn't you take the log of Both Sides right from the beginning?
Know the difference between exponent and power
Why should you cancel out logs
Maths teaches you rules and how to make them work in your favour.
I'd prefer to go with ln though,but good overall
Powerful
It is very useful sir
Nice working but note, as a good mathematician always let your "=" (equal to sign) align.
The working isnt neat. The sign should be on a straight line downwards.
Thanks for sharing
Which rule is this one again? When was it passed into law? Must you find error? 😅😅😂😂😂😂
Why do you have to introduce log?!
7 minutes is wild i did it in 1
Show your workings
He's trying to teach npc go compete somewhere else
Love it
Why introduce logs so late
Agreed. Couldve been done at step 2. Kick-down rule follows
I agree with you (too long). Maybe he was trying to show all sorts of students so that they could understand as well.
Exactly my thought, he could have introduced logs much much earlier
Content creation abi
@@ruhahabill1074 I see 😂
Nothing we get from this 😌
NOW!
This is all because numbers should never mix with letters, symbols and signs
Great staff thou I thought you’ll at the end simply say X= 2/4.5 which you wouldn’t even need a calculator for it
x=4.4
did you have a WhatsApp group for maths Olympiad
Bro could've used logarithm from the very start 😊.
That 0 where it come from?
A simple mathematics,,, why use more than ten steps. This a 4 steps solution.
If we were to use a calculator we would do something like this:
Give 1 to x
Then give 0.5 to x
Then give 0.4 to x
Then give 0.45 to x
Then give 0.47 to x
Then give 0.46 to x
The first one can be made by mind, just use 5 times your calculator. Isnt it easier?
what if you introduced the log earlier. Too long for nothing
Why you didn't introduce logarithm in the initial stage.
If so I won’t see the whole video. I thought it’s without log
Because math is step by step
You're intelligent than my mathematics teacher😅
Wow
Taking log of both side makes it useless
I don't agree with that style of calculation
It's OK bro
Same here
You introduced log very late
M0
A0
Alot of working though
For some time I thought its one of those that doesnt allow calculators lol why complicate an easy math
The tutor over delays
Wala😅😅

mistake plz where yo got 9..denominator should be 4..but it remains 2...
Rewatch again my dear he is correct
The answer 2 there and not 4 bcos the power was only on 3 but x was a power affecting both the numerator and denominator
Wrong
Pls is it only me that seeing this thing the work is not correct.I mean the step but I don’t know
You took long to apply log it should be done long ago and avoid unnecessary steps.
He is going slowly for some who have difficulty following...
You could have taken log of both sides since the beginning wtf
O que isso q esse cara está fazendo? Ñ entendi absoluramente nada!
You just had to add log from the 3rd step. You took the calculations way too far.
Your liying this apply log both side
X baraz me 0
Maths really is a log😢😂

This is shameful. Imagine a student going against time and decides to use your steps.
You made it look toooo long. Common.
Reading the bible is not a waste of time
The solution is wrong not correct. Bad interpretation on 4.5
😂solve without a calculator
👍
You make maths look silly. Simple equation in time and you search in eternity. Waste of time
You skipped a rule
Yh
Where do these things work? It's just wast of our time. If you know operations it's enough.

Is lie, calculation
Poor solution
Studying this kind of mathematics is totally wastage of time, it's not applicable in any place in your life. Totally useless
What a fool why wouldnt u take log both sides
Bro just keep it x equal 🟰 (log9-log2)/log2 . Approximation can mess up the whole Math and verification
