Answer:

=#19#

Explanation:

It is most important to count the number of terms first. Each term will simplify to a single answer and these will be added or subtracted in the last step.
Within each term - brackets must be done first.
Then do the stronger operations of powers and roots.
Then do multiplication and division.

#2(color(red)(36div4)) color(blue)(+9)color(lime)(-8)# has 3 terms.

=#color(red)(2xx9) color(blue)(+9)color(lime)(-8)#

=#color(red)(18) color(blue)(+9)color(lime)(-8)#

=#19#
