  • An abstract example how to solve negative exponents follows:
    ( Base ) −Exponent
    Base −Exponent
    1 Base+Exponet

There is one important exception. Dividing by zero is prohibited. The answer is undefined. Another way of saying this is if the base number is zero the problem can not be solved.

Now let's look at the alternate case where initially the number with the negative exponent is in the denominator.

1 Base−Exponet

Base +Exponent
