Answer:

#15#

Count the number of terms first. Each term will simplify to to a single answer and they are only added or subtracted in the last line.

Within in a term - do brackets first, then the strongest operations (powers or roots), and then multiplication and division.

#color(purple)(2^3)color(red)( + 8div4xx2)color(blue)(+3)" "larr# there are 3 terms.

=#color(purple)(8)color(red)( + (8xx2)/4color(blue)(+3)#

=#color(purple)(8)color(red)( + 4)color(blue)(+3)" "larr# add from left to right

=#15#
