Hiii..
here is ur answer :--
1) (35)^3 +(-25)^3+(-10)^3
let a = 35, b = -25 , c = -10
so, a+b+c = 0
35+(-25)+(-10)
= 35 -35
= 0
a^3+b^3+c^3 = 3abc
(35)^3 + (-25)^3 + (-10)^3 = 3*35*(-25)*(-10)
= 26250
2) (104)^3
= (100+4)^3
= (100)^3 +(4)^3 +3*100*4 (100+4)
= 1000000+ 64 + 1200 ( 104)
= 1000064 +124800
= 1124864
Hope it helps u!!
