Based on everyone's comments, this is what I have come up with:
--------------------
x ^^ y is right associative, and has a precedence intermediate between
multiplication and unary operators.
Is that consistent with math? I think in math they usually write
(-1)^n with parens.
See for example the sin power series here:

What's the rationale for going against math here?
Hmm. Several other languages give it that precedence. But you're right,
it should be even higher than unary. Between unary and postfix ?
Good catch, I missed that one in the original proposal. Between unary
and postfix sounds right. I would be extremely surprised if -2^^2
evaluated to 4, but I would have to think twice about i++^^2.
