Answer:
18
Explanation:
PEMDAS
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
If the expression contains parentheses, always solve what's in them first
then if there are exponents, solve them
then do any multiplication or division, from left to right
last, do any additon or subtraction, from left to right
In this problem all we have to do is subtract 8 and 5 to get 3 and then divide that into 54 to get 18
