Well, this is something new! When we write this result as a power of 4, we get 40 as our answer.
But does 40 have any meaning? The idea of zero 4’s multiplied together doesn’t see to make much sense, does it?
But now let’s pursue this problem further. We have divided 43 by 43 by using the rule for division of powers of numbers and arrived at 40 as the answer. Now let’s try doing this same problem by ordinary arithmetic, without using powers, and see what we get. Which answer is right?
