My teacher asked to do this step by step on how to get to the answer 27.

Do the inside of the parenthesis and then the outside

(5)
3³
3*3*3=27
27+5=32
then 32-25=7
7 is your answer

3=3 to the third power- Btw it only means that in this equation because I could not find a way to put the 3 over the 3 on the computer.

                                          3+5(2+3)-25
                                            3+5x5-25
                                             14x5-25
                                               70-25=50
                                                  

We’re gonna need a picture to refer to in order to figure it out. try reposting your question with the picture included.
