What is x 0, when x = 0 itself? In this complete guide, we will study the expression x 0 and what it means. Does the answer to x 0 always equal to “ 1 ” or are there some exceptions? What Is x^0 Equal To? X to the power of 0 is always equal to 1, which results in this formula: x 0 = 1.
Considering several ways in which we can define an exponential number, we can derive the zero-exponent rule by considering the following: x 2 /x 2 = 1. Considering the division rule, when we divide numbers with same base, we subtract the exponents. x 2 /x 2 = x 2 – 2 = x 0 but we already know that x 2 /x 2 = 1; therefore x 0 = 1.

When b is a positive integer, is defined to be the product of a multiplied by itself b times. The question is, what is the most natural way to extend this definition to the case when b =0? Here are several ways to see that the definition is the only reasonable one: Exponentiation satisfies the laws of exponents: .
$$0^x = 0, \quad x^0=1$$ both are true when $x>0$. What happens when $x=0$? It is undefined because there is no way to chose one definition over the other. Some people define $0^0 = 1$ in their books, like Knuth, because $0^x$ is less 'useful' than $x^0$.
We define $$e^x = \displaystyle \sum_{n=0}^\infty \frac{x^n}{n!}$$ which is absolutely convergent for any complex $x$, and only depends on us defining what $x^n$ means for the natural numbers and $0$.
