Se tivesse substituído por a e b no início ficaria bem mais simples. Chegaria em a = 3b. (If I had replaced it with a and b at the beginning it would be much simpler. It would arrive at a = 3b.)
10^0.5~3.16; LHS is 6.16^x + 0.16^x; Calculator: try x=2>37.97. close enough. Check video. Darn! I missed the -2 solution.
I want understand note
❤❤❤❤❤Nice and modern topic. What is the name of this property in mathematics?
F(x) - x^3 = - 3x^2 x^2 - 3x^2 = - 2x^2 - 2x^2 = 80 F'(x) - 2x^2 = - 4x - 4x = 80 x = 80/- 4 x= - 20 Demostrate. - 3*2*(-20) - 40 = 80
Girice 200g + Hambie - 3.50 euro, Papaline 200g + Hambie 120g (or 80-100g, I don't know, but I mean 120g is standard - 1.20 Euro, and Fulie 240g is standard - 2.00 euro) - 3.00 Euro, Hambie - 0.50 Euro. Can to buy only 1 Hambie per 200g. Is that good?!
🎉
Nice
Thank you sir 🙏⭐
Note that x = sqrt(3) - 1 is the solution to the equation x^2 = 2 - 2x, so x^8 = (x^2)^4 = (2 - 2x) ^4, expand and use x^2 = 2 - 2x as needed and you will eventually get x^8 = 16 (41 - 56x), substitute x = sqrt(3) - 1 and you will get the same result :)
Why not?: (√3-1)^8 =((√3-1)^2)^4=(3-1)^4=2^4=16?
Thanks a lot
Love this, looks perplexing to start with but is surprisingly simple.
Well done!
Really cool, can you show intergrade W function by the way
Grande spiegazione ma anche grande difficoltà nel leggere : poteva usare un pennarello che rendesse la scrittura visibile !
4095=4096-1=64^2-1^2=(64-1)(64+1)=(x^3-1)(x^3+1) x^3=64=4^3 x=4. 1/4^(-x)=4^x=4^4=256.
Excellent really enjoyed and understood your explanation. Thank you very much.
(x² + 9) (x + 3) (x − 3) = (x² + 9) (x² − 9) = x⁴ − 81 ³√(x⁴ − 81) = ³√(424 − 81) = ³√343 = 7
X^256 =4^x Find x
you made it so complicated
x = 12
I want to be a mathematician ...but need very very detailed explanation... step wise
Give explanation each and every step... So a weakest person or students can understand the mathematics... If you focus one question Make that understandable to below average students... That will be outstanding.... The students below average in mathematics... Design your methods and approaches ... likewise
Impressive😮

Nice working.
Before watching the video here’s how I solved it. The small triangle has 2 angles, which are vertical pairs of x ans y. the measures of the small triangle, will be (x+y+t)(i labeled angle t the top angle) X+Y= 130, because of simple division from the given equation. Angle T must be 50. Now, because of the lines of congruency the triangle is, the big triangle is isosceles. The 2 bottom base angles are congruent, and equal 130. Divide by 2 to get 65. Subtract that from 360, to get 295
nice

This was pretty simple but you made it more simple by your explanation 😉😊
Nice solution
So nice solve
Nice 👌
Nice work ❤
Another solution would be by decomposing 400 into prime factors. 400 = 2⁴ • 5² By comparison, we know that x would equal 2, and so would y, that is equal to x. Express 2⁴ as 2² • 2², and you get the answer. x = 2 = y
It should be written as (10y)^y, not 10y^y. Be careful on how it is presented.
172 it took me 10 secs xD
very good
I did it using another method Squaring both sides- X + (13 + X) + 2 sqrt(13X + X^2)=169 Solving the equation we get X + sqrt(13X + X^2) = 78 This equation is the same as the first one but multiplier by root(X) So we get root(X)=6 since the RHS was increased six fold and the LHS was increased by root(X) X=36
Why not square the original equation as is? Then, 2x + 13 = 169 X= 78 What did I miss?
I think it is wrong because if you wanna cancel the square root with power two you must put it in absolute which is not done here
I think that if the root is in the parentheses (so (√x)², not √(x²)), x cannot be negative because the answer has to be a real number (in this case, 13), and if x is negative it would be part of the complex numbers, u get me?
@@space_twitch1926yeah I got you but even at the end he put power two on radical x = 6 and said that x is 36 while my main idea for it would be +-36 I think if we had x>0 that could work Anyways...
@@pooria44u42 yea you're right, we would need more info
I did this and i got 78 as the answer. Don't you have to take square on both sides to get rid of the under roots?
isnt there actually two solutions? x= 121 and x= -121?. because if x<0 hes is gonna come out of that square root as |x|
No, you can't put a negative number under a square root. Otherwise you will get an imaginary number.
@@thesquarduck8397 you didnt get it, if x is a negative number and he is under a power of 2, its gonna become positive, under a square root, its gonna become the opossite number of the original x
@@erickhora8438 No it's square root that is under power 2, not the x itself. Also look at the original equation, x is not under a power of 2.
Beatiful solution
