Simplify:
a. %28X%5E4%29%2A%28X%5E5%29 When multiplying like-bases (X), you add the exponents.
%28X%5E4%29%2A%28X%5E5%29+=+X%5E%284%2B5%29 = highlight%28X%5E9%29
b. Z%5E9%2FZ%5E10 When dividing like-bases (Z), you subtract the exponents.
Z%5E9%2FZ%5E10+=+Z%5E%289-10%29=highlight%28Z%5E%28-1%29+=+1%2FZ%29
