Write 0.002349 in scientific notation.
Studentka2010 [4]

Hi! I'm happy to help!

To solve this, we first need to know what scientific notation is. Scientific notation is a way a number is written. You write it using a number ranging from 1 to <10. Then, you multiply this number by 10^{x}.

In order to make this number reasonable for scientific notation, you have to move the decimal a certain amount of places. In this case you move it 3 places to the right to make your number 2.349. Since we moved it 3 places to the right our x will be -3. (If we'd moved it 3 places to the left, our x would be positive 3.)

So now, we insert our numbers:

<u>2.349·</u>10^{-3}<u></u>

<u>You write 0.002349 like 2.349·</u>10^{-3}<u>, when it is in scientific notation.</u>

I hope this was helpful, keep learning! :D
