B. 2.646•10^14
C. 2.646•10^15
D. 2.646•10^46

Answer 1

The answer is very simple to get if you have a calculator. You first multiply
`3.6` and
`7.35`. You should get 26.46, now you move one decimal to the front which means you are multiplying 10 to it. Now you can refer the rest from below:


`2.646 * 10^(1) * 10^(9) * 10^(5)` Add the powers of ten

`2.646 * 10^(1+9+5)`

`2.646 * 10^(15)` This is your answer =)
