here is ur answer...

Answer 2

$if \: a + b + c = 0 then \: a^3 + b ^3 + c ^3 = 3abc$
Ans to question no.2
(28)^3+(-15)^3+(-13)^3
in this case,28+(-15)+(-13)=0
So,(28)^3+(-15)^3+(-13)^3=3×28×(-15)×(-13)=16380.
Ans to question no. 3
(1/2)^3+(1/3)^3-(5/6)^3
(1/2)+(1/3)+(-5/6)=0
so,(1/2)^3+(1/3)^3+(-5/6)^3=3×(1/2)×(1/3)×(-5/6)= -5/12.
Ans to que no.3.
(0.2)^3-(0.3)^3+(0.1)^3
in this case, (0.2)+(-0.3)+(0.1)=0
so,(0.2)^3+(-0.3)^3+(0.1)^3=3×(0.2)×(-0.3)×(0.1)=(-0.018).
