#### The Exponential Function

- The exponential function is defined as follows:

y=a^x, where a \in R^+\backslash {1}.

Note: ‘a \in R^+\backslash {1}’ means that could be any positive number, excluding 1.

Example

9=3^{2}=3 \times 3 is equivalent to log_{3}9=2.

8=16^{\frac{3}{4}}=\sqrt[4]{16^{3}}=\sqrt{\sqrt{16 \times 16 \times 16}}.
