What does negative 5 in parantheses to the 2nd power equal and can you explain what it would mean without the parantheses is it the same thing?
(-5)2 = 25. This is because multiplying two negative numbers together always leads to a positive number. Think about it like taking a negative amount of negative numbers, which switches them over to positive numbers. -52 = -25, because you are not multiplying negative 5 by negative 5, you are multiplying 5 by 5, and then multiplying that value by negative 1.
