Question

14. Without actual calculating the cubes, find the value of each of the following
(1) (-10)3 + (7)3 + (3)3​

Answer 1

Answer:

We know that ,

If x + y + z = 0 , then

x³ + y³ + z³ = 3xyz

Here,

x = (-10 ) , y = 7 , z = 3 ,

Now ,

x + y + z

= -10 + 7 + 3

= 0

Therefore ,

( -10 )³ + 7³ + 3³

= 3xyz

= 3× ( -10 ) × 7 × 3

= - 630

Therefore ,

The value of ( -10 )³ + 7³ + 3³

= - 630
