Question

Choose a term from the Key Vocabulary list above that best describes the given expression.

$6.2\times {10}^5$

Step-by-Step Solution

Answer

The given expression can be best described as a scientific notation.

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 &#215; 10 5 .

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.
