Q. Prove that if a number is tripled, then it's cube is 27 times the cube of the given number.

Answer 1

Hey !!

Here is your answer.. ⬇⬇

Let the no. be x..

➡ Given that if no. is tripled.

x × x × x = x^3

Its triple value = 3x
so,
3x × 3x × 3x = 27x^3

Hence, now take value of x=1

Then, 1 × 1 × 1 = 1

it's triple value = 3( 1 )

3 × 3 × 3 = 27

Hence ,it is proved that if a number is tripled, then it's cube is 27 times the cube of the given number.
