Hard Math Test

For the last problem, just type in the number followed by x10 followed by the power. You should be able to include the ^ sign. For the ^ signs it is just signifying that the previous number is being raised to the power of the following number. If you answer all of these on your first try without cheating (using a calculator) you are clearly very brilliant.
