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.
