Answer 2

Answer:

1. 1092727

Explanation:

1. 103×103×103

or (103)^3

or (100+3)^3

as (a+b)^3 = a^3 + b^3 + 3a^2 b + 3ab^2

apply the above formula

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

or 1000000 + 27 + 90000 + 2700

or 1092727.

Solve the next part same as this.. i am attaching the formula image for your reference.
