Question

Evaluate 102^3-2^3 using identity

Answer 1

a3 – b3= (a – b)(a2 + ab + b2)
(102-2) (102^2 + 102×2 + 2^2)
100× (10404+204+4)
100×10612
1061200

Answer 2

Answer:

1061200

Step-by-step explanation:

x^3-y^3 = (x-y) (x^2+xy+y^2

(102-2) (102x102+102x2+2x2)

100x(10404+204+4)

100x10612

=1061200
