Answer:
123
Explanation:
Follow the PEMDAS order of operations. Learn more below. We only see parenthesis, so let us solve that.
12.3 × [(2 × 1.7) + 6.6]
(2 × 1.7) solve the inner parenthesis
3.4 multiplied; remove the parenthesis
12.3 × [3.4 + 6.6]
[3.4 + 6.6] solve the next parenthesis (which is the outer one)
10 added; remove the parenthesis
12.3 × 10 now we can just multiply
123 is the simplification.
