Answer 1

Answer:

proved

Step-by-step explanation:

Given Prove that 2 the power 30 + 2 the power 29 + 2 the power 28 upon 2 the power 31 + 2 the power 30 - 2 the power 29 is equals to 7 upon 10

We can write this expression as

2^30 + 2^29 + 2^28 / 2^31 + 2^30 – 2^29

2^28(2^2 + 2 + 1) / 2^29(2^2 + 2 – 1)

2^28 / 2^29 (7 / 5)

2^28 – 29 (7/5)

2^-1 (7/5)

1/2(7/5)

= 7/10
