Sir, you also should mention the concept and limitation of it. 1.concept - binomial approximation 2.limitation - aqquracy decrease as gap between perfect squares increases . This also works in subtraction like writing root 15 as 4 - 1/8
I knew this trick because of Jeetu bhaiya (Learn and share faculty). And sir missed a thing that we have to find the closest perfect square root not only small perfect square root. For example:- √15= 3+6/6=4 (according to video method) but this is wrong We can do it like this:- √15=√(16-1)=4-(1×1)/(2×4)=4-1/8=3.875 (approximately) Because the closest perfect square root is 16 not 9. Thankyou for reading.
asal me sir ek mistake kiye hai. Unhe nearest bolna chahiye thha n ki chhota jaise Root 15 hai to 16 leke krenge n ki 9. Or kyunki jo liye ho wo bada root hai isliye minus hoga 4-1/8 ans correct

For solution of 2 problem you mentioned is to make formula more complex,
