Question

(-9)3 + (4)3 + (5) 3
​

Answer 1

Answer:

0 is the answer of ur question

Answer 2

Answer:

-540

Step-by-step explanation:

we know,

$a^3 + b^3 + c^3 = (a + b + c) (a^2+ b^2+ c^2 - ab - bc - ac) + 3abc$

=> if a+b+c=0, then a³+b³+c³ = 3abc

here in (-9)³+4³+5³ , we take a=-9;b=4;c=5

so a+b+c = -9+4+5 = 0,

so, (-9)³+4³+5³  = 3(-9)(4)(5)

                         = -540
