You can see that if you write the numbers in "regular" notation:

300.97 x 10^8 we need to move the decimal point 8 places so add 6 zeros- 30097000000.

3009.7 x 10^7we need to move the decimal point 7 places so add 6 zeros- 30097000000.

I can easily compute 25*28 in my head (and so can you!). I multiply 25 by 4 to get 100 and I divide 28 by 4 to get 7. So 25*28 = 100*7 which is easily seen to be 700.

Now if you have 300.97*10^7 (and you want this in Scientific Notation) you can divide 300.97 by 100 (or 10^2) to get 3.0097 and multiply 10^7 by 100 or 10^2 to get 10^9. So 300.97*10^7 = 3.0097*10^9.

This is a very powerful tool to have!
