how do I use order of operation to solve this?

Question

 5 + 4 (3²-4)

 

      2 + 3

 

 

 

kids came home with homework and no notes.  I understand PEMDAS.  and I understand that this problem will involve division since it is a huge fraction.   I came up with 5 as an answer.  is this correct?  

 

the other one that I wasn't sure about is:

 

       4 + 4

6 +  3  - 1   x 3          I came up with 12.  (figured the fraction should be treated like (4+4)/(3-1) so...do the parentheses first.  then, going L to R, x3, then add 6...  but, not sure.  help??

Answer 1

5 + 4 (32-4)
__________

 

   2 + 3

 

The numerator:

5 + 4(32- 4)

5 + 4(28)          parenthesis

5 + 112             multiply

117

The denominator:

5

 

117 / 5 

 

Not sure what the second one "looks like."
