$\huge\underline\mathfrak{answer}$

Explain: to show that 17640 is not perfect square.

when we group into pairs of equal factors, we are left with two factors 2 and 5 which cannot be paired.

hence,17640 is not a perfect square.

let's find out by doing factoring.

17640= 2×2×2×3×3×5×7×7

so, in the factors we are seeing that 2 and 5 don't have any pairs.

so, as we says that 17640 is not a perfect square.
