Answer 2

Given number is (50 + 21)(50^2 + 21^2 - 1050)

The Given number is in the form of (a + b)(a^2 + b^2 - ab).


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

Therefore (50 + 21)(50^2 + 21^2 - 1050) = 50^3 + 21^3

                                                                  = 125000 + 9261

                                                                  = 134261.


The required value is 134261.
