Question

how square and root get cancelled ?

Answer 1

hi friend,

Square and root get cancelled

For example, we take 4

we can write 4 as 2²

Now,take root.
√4
=√2²
We can write,
=(2²)^1/2
Now,Numerator 2 and denominator 2 get cancelled.

Thus,in short we directly say square and root get cancelled instead of this total process.

hope it helps
