#-8#

Explanation:

#-5^2+3(5)+2=-5^2+3*5+2#

Use the order of operations to figure out which operator to evaluate first.
Order of precedence:
1. Parenthesis
2. Exponent
3. Multiplication, Division (whichever comes first you evaluate)
4. Addition, Subtraction (whichever comes first you evaluate)

So looking at the expression, we must first evaluate the exponent.
#=-25+3*5+2#

Next, we do the multiplication operator.
#=-25+15+2#

Then, we do the addition operators.
#=-10+2#
#=-8#
