Question

this is the last time for today.. I appreciate the help <3 you guys are getting me through 8th grade. ;)

Answer 1

The value of c is 2 so we get 4²=1/16

Answer 2

I believe that it is -2. 4 squared is 16, however, they want 1/16. When the exponent is a negative number, the positive version (16) is turned into a fraction (1/16). I hope this makes sense. Try -2. Have a great night/day mate!
Or just put it in a calculator. Whatever works.
