Question

prove that2power30+2power29+2power28/2power31+2power30-2power29=7/10

Answer 1

Answer:

What you said is right answer is 7/10 it is true

Step-by-step explanation:

2 power 30 + 2 power 29 + 2 power 28 / 2 power 31 + 2 power 30 minus 2 power 29 is equals to 7 / 10

=2³⁰+2²⁹+2²⁸/2³¹+2³⁰-2²⁹

=2(2³⁰/2²⁸+2²⁹/2²⁸+2²⁸/2²⁸)/2²⁹(2³¹/2³⁹+2³⁰/2³⁹-2²⁹/2²⁹)

=2²⁸(2²+2+1)/2²⁹(2²+2-1)

=(4+2+1)/229-28(4+2-1)

=7/2(5)

7/10
