Question

What is exponential notation?

Answer 1

Exponential notation:

Exponential notation is a way of expressing the too large or too small numbers into a single number and $10$ raised to the power of the respective exponent. The power of the exponent can be either positive or negative form.

For Example:

$$\begin{gathered} 90000=9\times {10}^4 \\ 0.000018=18\times {10}^{-6} \end{gathered}$$

Thus, exponential notation is a way of expressing the too large or small numbers into a single number and $10$ raised to the power of the respective exponent.
