Question

How do you write $1.98\times {10}^{-4}$ in standard form.

Answer 1

Use the properties of the exponent to simplify the expression.

Given an expression $1.98\times {10}^{-4}$

$$\begin{gathered} 1.98\times {10}^{-4}=1.98\times 0.0001 \\ =0.000198 \end{gathered}$$

Hence,$1.98\times {10}^{-4}=0.000198$
