Question

Find the smallest number must be subtracted from 130 to make them perfect cube.​

Answer 1

Answer:

Solution. ∵ The next number to be subtracted is 91, which is greater than 5. ∴ 130 is not a perfect cube. However, if we subtract 5 from 130, we will get 0 on performing successive subtraction and the number will become a perfect cube.
