Question

Using suitable identity evaluate -32 cube +18 cube +14 cube

Answer 1

Answer:

Your answer is - 24192

Step-by-step explanation:

A = - 32, b = 18, c = 14

Then,

A^3 + b^3 + c^3 =?

(-32)^3 + (18)^3 + (14)^3 =?

➡️ We see,

A + b + c = 0

-32 + 18 + 14 = 0

➡️ We know, when A + b + c = 0

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

So

➡️ (-32)^3 + (18)^3 + (14)^3 = 3 ☓ [(-32) (18) (14)]

➡️ (-32)^3 + 18^3 + 14 ^3 = - 24192
