Answer 2

252= 2×2 × 3×3 ×7

The prime factor 7 does not appear in pairs. To make 252 a perfect square we need one more 7.

Hence, the smallest number by which 252 must be multiplied so that

the product is a perfect square is 7.

And, 252×7= 2×2 × 3×3 × 7×7

$\sqrt{252 \times 7 } = \sqrt{2 \times 2 \times 3 \times 3 \times 7 \times 7} = 2 \times 3 \times 7 = 42$
