Question

Find the smallest number by which 2560 must be multiplied so that the product is a perfect cube,
Find the smallest number by which 8788 be divided so that the quotient is a perfect cube.​

Answer 1

Answer:

2650=5×8×8×8

There is one 5 and three 8

Hence for perfect cube, there should be three 5

So the number has to be multiplied by 5×5=25

8788=4×13×13×13

For perfect cube, there are three 13, but there is one 4.

So if you remove 4, then 8788 will be a perfect cube.

So you have to divide 8788 by 4
