Question

Prove that if a no is tripled then its cube is 27 times the cube of the given no

Answer 1

easy

Let's assume that the initial number is a.

A1 = a³

Now let's multiply the initial number with 3
A2 = (3a)³ = 27a³ = 27 A1
A2=27(A1)
that means if we triple a number then the cube will be increases 27 times
