Question

By using suitable identities evalute (103)3


no.25

Answer 1

Given (103)^3.

We can write 103 as (100 + 3)^3.

We know that (a + b)^3 = a^3 + b^3 + 3a^2b + 3ab^2

                                       = 100^3 + 3^3 + 3(100)^2 * 3 + 3 * 100 * (3)^2

                                       = 1000000 + 27 + 90000 + 2700

                                       = 1092727
