What is your question(s)? I can try to help you
Basically if you have an exponent at the end of a 10,
![10^{7}](https://tex.z-dn.net/?f=%2010%5E%7B7%7D%20)
, then in the end the extended notation is going to have 7 zeros. So it'll be 10000000. Then you multiply whats in the rest of the equation together. There's the beginning :) I hope it helps.
