Answer 1

Hey

Here is your answer,

Your question is,
Prove that 2^30 +2^29 + 2^28/ 2^31+2^30-2^29 =7/10
(LHS). (RHS)

LHS = 2^30 +2^29 +2^28/ 2^31+2^30-2^29

Take 2^28 as common from the numerator and denominator.
=2^28 (2^2 + 2 +1) / 2^28 (2^3 +2^2 -2)
=4+3/8+4-2
=7/8+2
=7/10
=RHS

Hence proved.

Hope it helps you!
