Step-by-step explanation:

hi good morning.........

Answer 2

Answer:

-360

Step-by-step explanation:

Given:-

(-8)³ + (5)³ + (3)​³

suppose,

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

a + b + c = -8 + 5 + 3 = -8 + 8 = 0

If a + b + c = 0 then,   a³ + b³ + c​³ = 3abc   ( identity)

                            (-8)³ + (5)³ + (3)​³ = 3 (-8) (5) (3)

                                                        = -360
