1) 5^-1  =  1/5^1 = 1/5    we can put down the number that has negative exponent 
2)3^-3 = 1/3^3 = 1/ 27 
3) 4^4/4 = 4^3       (we simplify by4)  because  4x4x4x4 /4  = 4x4x4 
4) 8^4/8^0 = 8^4     (because 8^0 = 1 )
5) (-4)^8/(-4)^4  = (-4)^4   (we can subtract the powers if we have the same number )
6) g^9/g^15   = g^-6  (subtract the power )
1) 1/3^5 = 3^?
3^ -5
1/-125 = (-5)^?  
(-5)^-3
3) z^?/z^8 = z^-3
z^5
