difference of two perfect cube is 387 if the cube root of the greater of two number is 8 find the cube root of the smaller number

Answer 1

$<b><i>Heya !$

Here's your answer !!

______________________________

GIVEN THAT :

Difference of two perfect cubes = 387

Cube Root of greater no. = 8

_____________________________

TO FIND :

Cube Root of smaller number.

_____________________________

SOLUTION :

Let the smaller no. be x³

{ Since, it is a perfect cube and " x " denotes the cube Root }

Given that, cube Root of greater number is 8,

cube would be : -

=> ( 8 )³

=> 8 × 8 × 8

=> 512

_______________________________

A.T.Q.

THE EQUATION FORMED :

512 - x³ = 387

=> x³ = 512 - 387

=> x³ = 125

=> x = ${\sqrt[3]{125}}$

=> x = 5

______________________________

ANSWER :

The cube Root of the smaller number is 5
