so in your problem we start inside the parenthesis

3/ 8^2+5(6+5) so (6+5) = 11 now we put that in our parenthesis

3/ 8^2+5(11) next step is exponents so 8^2=36

3/36+5(11) now m/d so 3/36= 1/12(reduced by 3) and 5(11) (this is a way to show multiplication)= 55

1/12+55 now add = 55 1/12 is the answer for this make sure that for this problem you didn't miss anything for signs or if more was supposed to be divided it can make a big impact in your answer
