Question

PLEASE HELP!!!!
Which is equal to –(4 – 5)^2 + 1?

A.0
B.2
C.1
D.-1

Answer 1

Using PEMDAS it would be -1 .
First you do the parentheses which equals to (-1). Then you raise it to the second power which is 1 because -1 * -1 is 1. But then you have the negative symbol on the outside so it is -1.
