Answer: C
a* = 1 - a
(-1)* = 1 - (-1) = 2 so ((-1)*)* = 2*
So A and B are equal. And answer is C.
a* = 1 - a
(-1)* = 1 - (-1) = 2 so ((-1)*)* = 2*
So A and B are equal. And answer is C.

Need some help here. I solved it this way:
A --> [(-1)^(1-1)]^(1-1) --> [(-1)^1+1]^1+1 --> (1)^2 --> 1
B --> 2^(2-1) = 2
So, B > A.
is this right?
A --> [(-1)^(1-1)]^(1-1) --> [(-1)^1+1]^1+1 --> (1)^2 --> 1
B --> 2^(2-1) = 2
So, B > A.
is this right?
