Answer
$11$
Work Step by Step
Recall, in order to solve problems involving order of operations, we use the PEMDAS rule.
First Priority: P - parentheses and other grouping symbols
Second Priority: E - exponents
Third Priority: M/D - Multiplication or division, whichever comes first from the left to the right
Fourth Priority: A/S - Addition or subtraction, whichever comes first from the left to the right
Apply the exponents first to obtain:
$=5(2)(2) -4(2)-1
\\=5(4)- 8-1
\\=20-8-1$
Subtract next to obtain:
$=12-1
\\=11$
