We want to round the given decimal number and write the result as the product of a single digit and a power of 10.
0.000384509
Let's start by rounding the given number to the nearest 0.000 1. Since the digit in the hundred-thousandths place is greater than 5, we will modify the digit in the ${\color{#A800DD}{\text{ten-}}}$${\color{#A800DD}{\text{thousandths}}}$ ${\color{#A800DD}{\text{place}}}.'"`UNIQ--MLMath-4-QINU`"'
Finally we will write the above number as the product of a single digit and a power of10.To do so, let's first factor out4.$
