Question

by using suitable identity, find the value of
(a) (-6)^ 3 + 13^3 + (-7)^ 3
(b) (-21)^ 3 + (28)^ 3
(c) (9.8)^ 3 - (11.3)^ 3 + (1.5)^ 3
(d) (8/15)^ 3 + (-1/3)^3 + (-1/5)^ 3

Answer 1

a)(-10+4)³+(10+3)³+(-10+3)³
=-1000+64+1200-480+1000+900+270+27-1000+900-270+27
=1200+1000+1700+118-480
=4018-480
=3538 ans
b) c) d) in the so on.

Answer 2

Answer:

a)(-10+4)³+(10+3)³+(-10+3)³

=-1000+64+1200-480+1000+900+270+27-1000+900-270+27

=1200+1000+1700+118-480

=4018-480

=3538 ans
