Question

Evaluate without actual multiplication: (-4)^3 + (-3)^3 + 7^3​

Answer 1

Answer:

252

Step-by-step explanation:

taking a=-4, b=-3 and c=7

you can rewrite question as a^3+b^3+c^3

we know that when a+b+c=0,

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

applying that property here we get

a^3+b^3+c^3=3abc=3×-4×-3×7=252
