Answer 2

Step-by-step explanation:

prime factorization of 720 = 2×2×2×2×3×3×5

We observe that 5 has no more pair

Therefore we have to multiply 720 by 5 to get a perfect square

720 ×5 = 3600

Therefore √3600 = 60

Hence,5 is the smallest number that should be multiplied with 720 to get a perfect square
