# How do you write 890,000 in scientific notation?

Aug 5, 2017

$8.9 \times {10}^{5}$

#### Explanation:

Scientific notation is a way of writing very large or very small numbers using a power of $10$

It is written as $n \times {10}^{m}$

$n$ must be a number with one digit before the decimal comma,

ie $1 \le n < 10$

$m$ must be an integer.

In the number $8 \textcolor{b l u e}{90 , 000}$, move the decimal point $\textcolor{b l u e}{5}$ places to the left

$890 , 000 = 8.9 \times 10 , 000$

$= 8.9 \times {10}^{\textcolor{b l u e}{5}}$
