The answer is #0#.

#3 - (2^3 -: 1) + 5#

The operations are shown by PEMDAS:

First thing we have to do is take care of the expression inside the parenthesis , #(2^3 -:1)#

First, #2^3# is the same thing as #(2)(2)(2)#, or #8#.

and #(8 -: 1) = 8#

So now the expression becomes:
#3 - 8 + 5#

Addition and subtraction goes by whatever is most on the left, so it simplifies to:
#-5 + 5#

So the answer is #0#.

Hope this helps!
