7.8 • 10^8

1.5 • 10^9

(5^3)^2 • 5^0

Answer 1

780,000,000

1,500,000,000

15625

Explanation:

`10^(8)` = 100,000,000

7.8 x 100,000,000 = 780,000,000

`10^(9)` = 1,000,000,000

1.5 x 1,000,000,000 = 1,500,000,000

`5^(0)` = 1

(
`5^(3)`)² =
`5^(3)` x
`5^(3)` = 125 x 125 = 15625

15625 x 1 = 15625
