Question

1. dustin computed his family’s road trip as 4.43 × 10^3 miles. how many miles did dustin’s family travel on the road trip?

Explanation:

Step1: Recall scientific - notation rule

The scientific - notation $a\times10^{n}$ where $1\leq a < 10$ and $n$ is an integer. To convert $a\times10^{n}$ to standard form, when $n>0$, we move the decimal point $n$ places to the right.
For $4.43\times 10^{3}$, since $n = 3$, we move the decimal point 3 places to the right.

Step2: Perform the conversion

Starting with 4.43, moving the decimal point 3 places to the right gives us 4430.

Answer:

4430
