You can put this solution on YOUR website!
Think of 78,000,000 as 78,000,000.0
Start moving the decimal place left until you have a number that is between 1 and 10.
Eventually you will get 7.8.
Count how many times you moved the decimal.
You moved the decimal place 7 times so in scientific notation this is:
7.8 x 10^7
