Question

Prove that if a number is tripled, then its cube is 27 times the cube of the given number.​

Answer 1

Answer:

let the no. be x, if tripled will be 3x

then, (3x)^3= 27 x^3

Answer 2

Answer:

Let us assume that the original number= x

Its cube=(x)³

= x³

If the original number is tripled then the new number=3× X

Cube of the new number= (3x)³

=3X × 3X × 3X

27x³

Therefore,

Cube if the original number: Cube of the new number which is tripled

→ 1:27

Hence, the cube of the new number is 27 times the cube of the original number.
