Question

How do you write $0.0001$ in scientific notation?

Answer 1

Express the given number in scientific notation

The given number: $0.0001$.

$$\begin{gathered} \Rightarrow 0.0001=\frac{1}{10000} \\ \Rightarrow 0.0001=1\times \frac{1}{10000} \\ \Rightarrow 0.0001=1\times \frac{1}{{10}^4} \\ \Rightarrow 0.0001=1\times {10}^{-4} \end{gathered}$$.

Therefore, $0.0001$ can be expressed in scientific notation as $1\times {10}^{-4}$.
