$48$
Work Step by Step
RECALL:
The order of operations follow the PEMDAS rule:
First Priority: P - Parentheses or grouping symbols
Second Priority: E - Exponents
Third Priority: M/D - Multiplication or division, whichever comes first from the left
Fourth Priority: A/S - Addition or subtraction, whichever comes first from the left
Simplify within the parentheses to have:
$=(3\cdot 3 \cdot 3 - 4) +5^2
\\=(27-4) + 5^2
\\=23 + 5^2$
Apply the exponent to have:
$=23 + 5(5)
\\=23+25
\\=48$
