When you do not see the decimal just put it at the very end of the problem!
So now 5,098,000.
Now we need to move the decimal over to make this problem greater than 1 and less than 10. So if we but the decimal Right after 5 we have 5.098 which is greater than 1 and less than 10.
So now we write it out like this
5.098*10^x
let's find x.
X is how many times we moved the decmal over, in this case 6.So now
5.098*10^6
Does this help?
