A couple of comments:
1) The character used to indicate exponentiation in plain text is the caret (^), above the 6 on most keyboards. This character (∧) signifies a logical AND, which is not appropriate for your use here.
2) Variable values are missing for problems 4 and 5. We can guess that the missing value in problem 4 is either -0.1 or 0.6.
