hi friend,

here is your answer

Answer:

3 is the smallest number by which 3087 must be divided so that the quotient is a perfect cube. we have to find the smallest number by which 3087 must be divided so that the quotient is a perfect cube. Since the number 3 has not triplet, Therefore we need to multiply 3087 by 3 to make it a perfect cube.

Step-by-step explanation:

3087=(3)

2

×(7)

3

In this factorisation, we find there is no triplet for 3.

∴ 3087 does not have a cube root.

∴ The smallest number by which 3087 is to be multiplied so that the product has a cube root is 3.
