Express the given number in scientific notation.
$2300000$

Short Answer

Expert verified

The required scientific notation is $2.3 \times 10^{6}$ .

Step by step solution

Step 1. Define an integer.

An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

Step 2. Define scientific notation.

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

Step 3. Express the number 2300000 in scientific notation.

Move the decimal point until it is right of the first non-zero digit.

$2300000 \to 2.300000$

So, $a = 2.300000$

The decimal point is moved 6 places to the left.

So, $n = 6$

Hence,

role="math" localid="1647800692235" $\begin{matrix} 2300000 = 2.300000 \times 10^{6} \\ = 2.3 \times 10^{6} \end{matrix}$

Therefore the required scientific notation is $2.3 \times 10^{6}$ .
