Question

hi sir/ma'am can you prove that if a no tripled then it's cube is 27 times the cube of the given no​

Answer 1

Let the no. be x and the cube of the no. be x³

Now Add the no. x and find the cube of resultant no.

x+x+x = 3x

the cube of 3x = 3x•3x•3x = 27x³

The ratio is x³:27 / a³

which gives 1:27

Hence proved, If the no. is tripled then it's cube is equal to 27 times cube of the no.

Answer 2

Let the number is x

If number is tripled then number = 3x

cube is x³ and (3x)³

x³ and 27x³

So, it is always 27 times the cube.

So, it is always 27 times the cube.Hence, proved.
