Question

12.
Is 53240 a perfect cube? If not, then by which smallest natural number
should be divided so that the quotient is a perfect cube?​

Answer 1

Answer:

So, 53240 is not a perfect cube. In the factorisation 5 appears only one time. If we divide the number by 5, then the prime factorisation of the quotient will not contain 5. Hence the smallest number by which 53240 should be divided to make it a perfect cube is 5.
