3.9

Explanation:

The order of operations are: PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction)

so..................

#5^2# is first and that equals 25
Now we have #25 + 6.2/(-2) - 6(3)#
Next we have division or multiplication:
#25 + (-3.1 ) -18#
Now we just add them together!
#25 - 3.1 -18 = 3.9#
Notice that # 25 + (-3.1)# is just #25-3.1#
