Question

1. 4.5 × 10⁶ μm → m

Explanation:

Step1: Recall unit conversion factor

We know that \(1\ \mu\text{m} = 10^{- 6}\ \text{m}\). So to convert micrometers to meters, we multiply the value in micrometers by \(10^{-6}\).

Step2: Perform the conversion

Given the value is \(4.5\times10^{6}\ \mu\text{m}\). We multiply it by the conversion factor:
\[

$$\begin{align*} 4.5\times 10^{6}\ \mu\text{m}&=4.5\times 10^{6}\times(10^{-6}\ \text{m})\\ &=4.5\times(10^{6}\times 10^{-6})\ \text{m}\\ &=4.5\times1\ \text{m}\\ & = 4.5\ \text{m} \end{align*}$$

\]

Answer:

\(4.5\ \text{m}\)
