How to simplify 1/3 (4-5)^2-4

Can you do me a step by step process?

thanks very much :D

If you type that right, assuming that its 1/3*(4-5)^2-4

the answer is: -3

i remember asking people for help like this idk if im reading the question right because of bad format you are typing it in

1/3(-1)^-2
1/3(1)
1/3

im not 100% on that but that is my best guess
