Question 118664
when quantities having the same bases are divided, the exponents are subtracted


(2^6)/(2^2)=2^(6-2) ___ (2^6)/(2^2)=2^4 ___ 64/4=16


if the exponents are the same ___ (2^3)/(2^3)=2^(3-3) ___ (2^3)/(2^3)=2^0 ___ 8/8=1


in this case, a=2 ___ a can be any value except for zero (division by zero is undefined)
