Question

without actually calculating the cubes find the value of (-13)^3 +(8)^3+ (5)^3​

Answer 1

Answer:

The value of the given expression is -1560

Step-by-step explanation:

Concept to be known =

When a + b + c = 0

Then a^3 + b^3 + c^3 = 3abc

Here,

a + b + c = -13 + 8 + 5 = 0

Therefore,

(-13)^3 + (8)^3 + (5)^3 = 3(-13)(8)(5)

= -1560
