# What is 0^0?

## Today's Algebra Books

Pick up a high school mathematics textbook today and you will see that 00 is treated as an indeterminate form. For example, the following is taken from a current New York Regents text [6]:

We recall the rule for dividing powers with like bases:

 xa/xb = xa-b (x not equal to 0) (1)

If we do not require a > b, then a may be equal to b. When a = b:

 xa/xb = xa/xa = xa-a  = x0 (2)

but

 xa / xa = 1 (3)

Therefore, in order for x0 to be meaningful, we must make the following definition:

 x0  = 1 (x not equal to 0) (4)
Since the definition x0 = 1 is based upon division, and division by 0 is not possible, we have stated that x is not equal to 0. Actually, the expression 00 (0 to the zero power) is one of several indeterminate expressions in mathematics. It is not possible to assign a value to an indeterminate expression.
