HOW DO YOU WRITE NUMBERS IN SCIENTIFIC NOTATION?

2. ## scientific notation

Here are a few examples of scientific notation. Let me know if it makes sense.
$1 * 10^{-1} = 0.1$
$2 * 10^{-1} = 0.2$
$2 * 10^{-3} = 0.002$
$2 * 10^{3} = 200$

3. I Understand It Now, Thanks!

it should be $2\cdot10^3=\bold{2000}$

First of all, release your CapsLock.
All upper-case letters is impolite . . . it's shouting.

How do you write numbers in scientific notation?

A quantity in scientific notation is a number $n,\;1 \leq n < 10,$ times a power of 10.

Examples

. . $(a)\;238,000 = 2.38 \times 10^5$

. . $(b)\;0.00057 \,= \,5.7 \times 10^{-4}$

In example (a), $238,000$ was transformed to $2.38$
. . by moving the decimal point (far right) five places to the left.
In effect, we have divided by $100,000$
. . so we multiply by $100,000 = 10^5$

In example (b), $0.00057$ was transformed to $5.7$
. . by moving the decimal point four places to the right.
In effect, we have multiplied by $10,000$
. . so we divide by $10,000$ ... or multiply by $\frac{1}{10,000} = 10^{-4}$
