Answer 1

B) 2.622 x 10^14 hopes this help i am late for the answer ^-^'

Answer 2

we have

`(3.8*10^(8))*(6.9*10^(5))`

Combine like terms

`(3.8*10^(8))*(6.9*10^(5))=(3.8*6.9)*(10^(8)*10^(5))`

Multiply

`=(26.22)*(10^(8+5))`

`=(26.22)*(10^(13))`

`=(2.622*10)*(10^(13))`

`=(2.622)*(10^(13+1))`

`=(2.622)*(10^(14))`

therefore

the answer is the option B

`(2.622)*(10^(14))`
