Question

prove that if a number is tripled , then its cube is 27 times the cube​

Answer 1

Explanation:

When the number is tripled, that is, 3a, then the cube of the new number will be 27(a^3). We need to prove that the new number is 27th times the given number. Therefore, (a^3) : 27 / (a^3), which gives 1:27. Hence, it is proved that the number is 27th times the new number.
