See the step by step solution

## Step 1. Define an expression.

A mathematical expression is a combinations of numbers and variables ordered with mathematical operations.

## Step 2. Define scientific notation.

A number written in scientific notation is of the form $a×{10}^{n}$, where $1\le a<10$ and $n$ is an integer.

## Step 3. Write the best description for the expression, 6.2×105.

Compare the expression, $6.2×{10}^{5}$ with $a×{10}^{n}$.

This gives $a=6.2$ and $n=5$.

Since $1\le 6.2<10$ and 5 is an integer.

So, it can be termed as a scientific notation.

Therefore the given expression can be best described as a scientific notation. ### Want to see more solutions like these?
