Answer» HEYA......!!!

___________________________


We have to find the VALUE :

=>  (28)³ + (–15)³ + (-13)³


Let -» a = 28

B -» -15

c -» -13


=> a + b + c = 0

If -» a + b + c = 0. Then a³ + b³ + c³ = 3abc



→ 28)³+ (–15)³ + (-13)³ = 3(28)(-15)(-13) = 16380


→ (28)³+ (–15)³ + (-13)³ = 16380


Answer = 16380
