First plug in -2 every where you see a x
5!(-2)3-2!+7
now solve the thing in the absolute value bars.
5!-6-2!+7
5!-8!+7
Take the number out of the absolute value bars. Since anything in a absolute values taken out, it will be positive, for ex:!2!=2&!-2!=2:
5*8+7
Simplify the problem using PEMDAS.
Since m (multiply) comes before a (adding), we multiply first
so 5*8 becomes 40
40+7
add
47
Answer: 47
