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

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

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

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

ie $1 \leq n < 10$ $1<=n<10$

$m$ $m$ must be an integer.

In the number $8 90, 000$ $8color(blue)(90,000)$ , move the decimal point $5$ $color(blue)(5)$ places to the left

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

$= 8.9 \times 10^{5}$ $= 8.9 xx 10^color(blue)(5)$
