Question

Prove that if a number is tripled then it's fine 27 times the cubes of the tube number

Answer 1

Let's take a number "a".
It's cube =a³

If we increase the number three times then it becimes "3a"
and it's cube becomes
=(3a)³
=3³a³
=27a³

As we can see if we increase a number by three times, it's cube increases by 27 times.

Heya ✋

Let see your answer !!!!

Let the number be x. Then,

$cube \: of \: the \: number \: = x ^{3}$
When the number is tripled then it become 3x.

Again cube of the number

$(3x) ^{3} \\ = 27x ^{3}$

It is proved.
