What the people above wrote is correct but it can also be
-(5)^2 -3
-25 - 3 = -28
-5^2 = -1 x 5 x 5
parentheses are very important ;). Did you mean (-5)^2 or -5^2?

Anything to the 2nd power is squaring the number. Any negative number (-5) will turn positive when it is squared/multiplied by itself (-5 x - 5 = 25, same as 5x5=25)..
25-3=22

negative five to the power of 2 times negative 3? think of it like this -5 times itself twice is 25. 25 times negative 3 equals negative 75 because a positive times a negative is always negative

-5squared is -25 (the - sign is only included when you square it if it looks like this [-5]^2
then subtract three
(like add three plus 25 and put a negative sign in front of it...)
hope it helps!
