2.34 xx 10^5

Explanation:

Scientific notation is where you write a number so that it is some number between 1 and 10 that is multiplied by 10 to a power.

Looking at 234000.0, I know that I need to move the decimal point over until I have a number between 1 and 10. Let's begin:

Move over once: " "23400.00

Move over twice: " "2340.000

Move over three times: " "234.0000

Move over four times: " "23.40000

Move over five times: " "2.340000 -> this number is between 1 and 10!

So I know the number part is 2.34 and since I had to move the decimal place over to the left 5 times the next number is 10^5

So 2.34 xx 10^5.
