Answer 1

For part A, you should be able to simply add up the decimal number first, then add up the exponent (in this case, that'd be 24+22). Do that please.

Answer 2

46?

Answer 3

Yep, now add up the first parts of each number. (The decimal numbers)

Answer 4

13.31

Answer 5

Yep. But now, you have to convert that to scientific notation. Restated, your current number is "13.31 x 10^46", but in sci notation, you can have only one number in front of the decimal, so convert "13.31" to sci notation. NOTE: The newly created "10^1" must be added to the "10^46". SO, restate that for me.
