write the number using a power of 10.
0.00079

Explanation:

Step1: Recall scientific - notation rule

A number in scientific notation is of the form $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Step2: Move the decimal point

For the number $0.00079$, move the decimal point 4 places to the right to get $a = 7.9$. Since we moved the decimal point 4 places to the right, $n=-4$.

Answer:

$7.9\times10^{-4}$
