Answer:
1/2
Step-by-step explanation:
First simplify the first part of the expression
1(2^-1-^2+-1^2-^-1) 2^(-1) is 1/2, -1^2 is 1, Simplify the terms with exponents
1(1/2-2+1--1)
I am going to assume that the carrot before the 2 is a typo because you cannot raise the - symbol to a power. I will also assume that the ^ before the last -1 is a typo because again, you cannot raise the - symbol to a power.
1(1/2)=1/2
