Question

What will be it's answer?

Answer 1

Step-by-step explanation:

= (2^30 + 2^29 + 2^28)/(2^31 + 2^30 -2^29)

= 2^28(2²+2+1)/2^29(2²+2-1)

= (4+2+1)/2*(4+2-1)

= 7/2*5

= 7/10

Answer 2

Step-by-step explanation:

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

2^28 ( 2² + 2 + 1 ) / 2^29 ( 2² + 2 - 1 )

2^28 ( 4 + 2 + 1 ) / 2^29 ( 4 + 2 - 1 )

7 / 2(5)

7/10 = 0.7
