Question

find ghe least number by which 12250 should be multiplied to get a perfect square​

Answer 1

Answer:

10

Step-by-step explanation:

12250 on factorization gives $5^3 * 7^2 * 2$

You need even number of factors for each prime number

Therefore, we need an extra 5 ($5^3 -> 5^4$) and an extra 2 ($2^1 -> 2^2$)

therefore, the number required is 5*2

= 10
