To write this as scientific notation, we have to go left until we have 1 digit. So, the decimal point will be at:
5 . 401200
Now, we mutliply this with 10 to the power of n.
n would be the number of times we moved left.
We moved:
6 times!
Thus, we can write this as:
[tex]5,401,200=5.4012\times10^6[/tex]
