isn't 2x2 going to be 4? you wrote 2, whixh one's correct?

[@namanmishraatyt]

if you are talking about 1:40 , he means that the square of 3 is 9 and the square of 2 is 4. If you see this is written as 9√4 and it means 9 and the square root of 4. As square root of 4 is 2 so it becomes 9x2 removing the under-root bracket.

Small question sir, in part (a) where you are evaluating 2ab,wasn't the 2 supposed to multiply by 1(b) also after being multiplied by 3root2(a)?
