Question

without actual multiplication find the value of (17) cube +( - 12 )cube +( - 5) cube

Answer 1

here a=17,b= -12 , c= -5
a+b+c=17-12-5
=5-5
=0
If a+b+c=0 then (a)cube+(b)cube+(c)cube=3abc
therefore (17)cube+(-12)cube+(-5)cube=3(17)(-12)(-5)
=51*60
= 3060

Answer 2

Answer:

Here a=17,b= -12 , c= -5

a+b+c=17-12-5

=5-5

=0

If a+b+c=0 then (a)cube+(b)cube+(c)cube=3abc

therefore (17)cube+(-12)cube+(-5)cube=3(17)(-12)(-5)

=51*60

= 3060
