problem — divisors analysis —

think, there should be more explanation on how this is done — have to carefully divide the exponent by 2

case1 — all divisor count is even

can simply find the square root of number by considering only half count,

case2 — there is atleast one divisor with odd count —

as this divisor occurs in half the total divisors,

considering only half count means dividing total divisors by 2,
