Answer 2

Step-by-step explanation:

130-1=129,129-7=122-19=103,103-37=66,66-61=5 <br> The next number to be subtracted is 91 which is greater than 5. Therefore the process of successive substraction does not give zero Hence 130 is not a perfect cube. If we subtract 5 from 130 the above process will give zero after 5 successive subtraction <br> Therefore 130-5=125=
