4. (-5) squared is 5 squared including the - sign which is equal to 25. -5 squared is 5 squared without including the - sign which is equal to -25.

Step-by-step explanation:

#4.

When there is a parenthesis around a number and the sign then the sign is part of the squaring. In this case (-5) squared means, -5 x -5 = 25 (negative times negative equals positive).

When there is no parenthesis around a number and the sign then the sign is pot part of the squaring. In this case -5 squared means -(5x5)= -25 (positive times positive equals positive, add the - sign that is outside the parenthesis and the answer becomes negative)
