I need to know if my answer is correct for the following two problems.

3 squared 189 divided by 3 squared 7 = 27

problem #2...
9 3 squared 3 - 2 3squared 3 = 5

Please let me know if these are correct. thanks for all your help.

You are misspelling the subject.

If you mean 3^2*189/[(3^2)*7)] for the first question, the answer is 27.

I do not understand your order of operations in
9 3 squared 3 - 2 3squared 3

If you mean
9*(3^2)*3 - 2*(3^2)*3, the answer is
7*27 = 189
You need to learn to use parentheses when the order of operations is unclear.
