7) i will give u example for this

Directrix (directrix):

On number 7, the 100^(a/b) question, we are not given any information regarding the numbers a and b other than b is not 0 and a>b. Would something like 100^(1/-1) = 100^(-1) = 1/100 be a counterexample to option D? I realize that the indices of radicals are positive integers, but the problem is not given in the context of radical expressions.
