already tried that. google calc. isn't always necessarily correct...but thanks for the attempt!
Since I'm not a math tutor, I checked with one of our experienced math tutors, and he agreed that Google is correct about this problem.

you must have been reading my problem wrong though...? I'm saying 2 to the -2 power
We understand and read your problem correctly. I copied and pasted your problem into the Google search box. Are you disputing both Google and BobPursley?
