@@SkanCityAcademy_SirJohn Sir why do you cancel the denominator part of +10(√5√2)-10(√5√2) why can't you just make full calculations of it jus like the numerator side ...... If you can divide those then I think you will have to do the same to the numerator
@@SkanCityAcademy_SirJohn yes I know but you should have make full calculations of it and it will still be the same thing like saying +10-10(√5√2)(√5√2) then we will later cancel them off because they are same with no whole number holding them...... I love you broda and your workings is clear..... I already subscribed to your channel
I fully agree with social sir cause simply even in this video th-cam.com/video/VpgRJEbXd6M/w-d-xo.html that you made the conjugate sign changes both in num and denominator with the same sign
@@SkanCityAcademy_SirJohnHe means, when you multiply the denominator and change the signs e.g first question, 2√5 + 5√2÷2√5 + 5√2 You changed the signs from - to + when multiplying the denominator I can't explain it because I can't write down the expression here
Well they could, but the idea is to know how it's done basically, considering the right approach and steps. When you master it, you can find so many ways around it
Don't get yourself confused, the right thing is what you have out there... If something is not clear, kindly state the time in the video and let me address it, because I don't really get your question.
When finding a conjugate, and the sign is negative you change it positive and when is positive you change it to negative 👍👍👍
Yes please
Go back to elementary and learn your maths
You guys can follow the workings it's correct but still confusing but still okay.... love you bro
Where is the error?

@Pastor_Moore001 because they cancel out, okay. And that's the right....

You're absolutely correct
Understood im

thats nice. thanks so much
You're welcome
@@studiesonly1 where do you watch from?
Means?
Which country do you come from?
he is 100% correct
Thanks so much
Nice explanation thanks for your suggestion😊
You are welcome
Whoever is saying this is wrong then answer the right answer then.
Ur working is 100% wrng sir
Are you sure you are not wrong yourself?
Kindly go through again and revert your statement.
I fully agree with social sir cause simply even in this video th-cam.com/video/VpgRJEbXd6M/w-d-xo.html that you made the conjugate sign changes both in num and denominator with the same sign
Are you aware that anytime you want to rationalize a surd you multiply both num and deno by conjugate of the denominator?
Exactly thanks for observing well
Why do you know it's addition when writing the second formula?
When the expression was :70 +20 root 10 all on 30 and how did you cancel the 2 0s at the numerator when the denominator is 30 with only one 0 ?
You factor out 10 both at the numerator and denominator. So it becomes
10(7+2sqrt(10)) / 10(30
10 cancels out 10
Very good thank u sir😊
You are most welcome
Can you explain how did you factor out the zeros in the last step ?
you have (70 + 20 root (10))/ -30
= 10/10 * (7 + 2(root 10))/-3
@@SkanCityAcademy_SirJohn I also don’t understand that part too the ending
Sir can you explain the rationalizing factor in questions related to byju's 9th IIT
Okay but please it would be best if you provide me with the questions
Pls hw did u get de final answer to be positive 3
The denominator is still negative 3. Just that we have represented in a more nicer way, leaving -1 outside the bracket. It's still the same thing
Tnx he is correct
Thank you my brother.
Yes
root 5 multiplied by root 5 is 25
that is incorrect, root 5 * root 5 is 5
how the sins changes
I don't really get your question
@@SkanCityAcademy_SirJohnHe means, when you multiply the denominator and change the signs e.g first question, 2√5 + 5√2÷2√5 + 5√2
You changed the signs from - to + when multiplying the denominator
I can't explain it because I can't write down the expression here
Any shorter solution to this
Yes, in fact with experience you can skip steps

Iam professional
Is there any simpler way to simplify this
Well they could, but the idea is to know how it's done basically, considering the right approach and steps. When you master it, you can find so many ways around it
Please my son is confused
what is the cause of the confusion please?
I don't know what and where? But i feel like you made error
No please, I haven't made any error, whatever you see there is correct
I think you have gotten the conjugate wrong sir.. I think on both denominator and numerator it’s suppose to be +.
Don't get yourself confused, the right thing is what you have out there... If something is not clear, kindly state the time in the video and let me address it, because I don't really get your question.
I'm confused
At which point
That's wrong
what is wrong? Kindly put down what you think is right
Says the guy watching this because they don't understand
Too long
Sorry about that. Anyways thanks for watching. Will revert in subsequent videos.
Extra ordinary wrong
What do you suggest is wrong
it's correct. surds can be really confusing if enough attention isn't paid.
