Question

Two questions that have to do with Evaluation Please help. I will post them in the box below.

Answer 1

\[[(21+6)-3^{2} ] \div9\] and
\[4-28\div7+3^{2}\]

Answer 2

Do the PEMDAS method. That will help you. But since there is a parenthesis before the bracket, then you still do the parenthesis and with that sum subtract it to 3^2.

Answer 3

I'm confused -.-

Answer 4
