Question

a power 1 upon 3 + b power 1 upon 3 + 3 power 1 upon 3 is equal to zero then find the value of a + b + C whole cube

Answer 1

Answer:

3abc

Step-by-step explanation:

a/3+b/3+c/3=0

(a+b+c)/3=0

a+b+c=0

a+b=-c (i)

cubing both sides we get:-

(a+b)3=(-c)3

a3+b3+3ab(a+b)=(-c)3 #(a+b)=-c

a3+b3-3abc=(-c)3

a3+b3+c3=3abc
