$-22$.
Work Step by Step
The given expression is
$=5+3^2\left [6-\left ( 4+\frac{12+3}{6-3} \right ) \right]$
Solve the fraction in the parentheses.
$=5+3^2\left [6-\left ( 4+\frac{15}{3} \right ) \right]$
Reduce the fraction in the parentheses.
$=5+3^2\left [6-\left ( 4+5 \right ) \right]$
Perform the operations in the parentheses.
$=5+3^2\left [6-9 \right]$
Perform the operations in the square bracket.
$=5+3^2\left [-3 \right]$
Calculate the exponent.
$=5+9\left [-3 \right]$
Multiply.
$=5-27$
Subtract.
