Answered by Steve
#1. 7^(9-3) = 7^6
NOT 7^(9/3) = 7^3
subtract exponents when dividing numbers. What you have is

7*7*7*7*7*7*7*7*7
------------------------
      7*7*7

only three of the 7's cancel

#2
z^8/z^12 = 1/z^4 = z^-4
So, D, not C

#3 ok

#4 not sure what that trailing 2 means, but
a.b^-2/b^4 = (1/b^2)/b^4 = 1/b^6
b.w^5/w^-3 = w^5 * w^3 = w^8
c.5^3/5^5 = 1/5^2
d.4^7/4^7 = 4^0 = 1
Looks like A and C both work.
