    If -5 is in pasnetheser, yes! Because when you multiply 2 negative numbers you get a positive number. But when you multiply 3 negative numbers you get a negative number. If the -5 is not in parentheses and there is an exponent of 2 next to the 5, then you are only squaring the 5 (not the -5), so the answer would be -25.
