Question

Find the smallest number by which 1125 must be multiplied so the product is a perfect square also find the cube root

Answer 1

Answer:

Smallest number = 3

Step-by-step explanation:

1125 = 3×3×5×5×5  (find with long division method/prime factorisation method)

as you can see 3 does not appear three times as the number 5.

Therefore, 1125×3 = 3×3×5×5×5×3

So, when we multiply the number 1125 with the smallest number 3 (in this case) we get the perfect cube.

Cube root of the new number is 3375 = 3×3×3×5×5×5
