Use the order of operations represented by PEMDAS: parentheses, exponents, multiplication and division, addition and subtraction.

#-7-(2^4-:8)# =

Do the operations inside the parentheses first.

Raise #2# to the power of #4#.

#2^4=16#

#-7-(16-:8)# =

Next complete the division.

#16-:8=2#

Finally subtract #2# from #-7#.

#-7-(2)=-9#

#-7-(2^4-:8)=-9#
