Answer 2

SOLUTION :

Heya !!!

This is your answer.

Given :

3 + 5 + (-8) = 0.

Then,

3³ + 5³ + (-8)³ = ?

Using, identity...

If a+b+c=0, then a³ + b ³ + c³ = 3abc

Let a = 3, b = 5 and c = -8.

Here, a + b + c = 3 + 5 + (-8) = 0.

Then, a³ + b³ + c³ = 3³ + 5³ + (-8)³

= 3× 3 × 5 × -8

= 9 × -40

= -360
