The first photo is a little unclear. However, using what you put in the question, I can decipher some of it.

As we are not allowed to give you the answers directly, I would only be able to give you hints.

Question 1: this is a fraction. no b term. Look at the power of indices as clues.
Question 2: look at the power of indices. no b term
Question 3: cancel down the fraction. no b term
Question 9: break the subtraction up.

If you have problems with the other questions (since you only asked for help with these specifically), let me know.
