Answer 1

if you were in an algebra class I might help, but this is precalc. If you can't help yourself with these, go drop the class. By the time you typed all these in, you probably could've looked up all the dumb rules in your textbook. YOU WILL NOT SURVIVE PRECALC IF THIS IS WHAT YOU HAVE TO RESORT TO. harsh I know, but give me a break

125

7) (8) ^ -2/3

1/64

8) (25) ^ -3/2
