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 $a\times {10}^n$, 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,$6.2\times {10}^5$ with $a\times {10}^n$.

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.
