Answer
6
Work Step by Step
We first plug 2 in for m and 6 in for n. The exponent tells us the number of times we multiply the number by itself. According to the order of operations, we simplify inside of parentheses, then we simplify powers, then we multiply and divide, and finally, we add and subtract. When we do this, we find:
$3 \times 2^{2} - 6 = 3 \times 4 -6 = 12-6 =6$
