Work Step by Step

We have a value of 40,500,000.00. In order to put this number into scientific notation, we must move the decimal point from the end of the number so that it is right after the 4. We must count how many places we move the decimal point. We then take the new number (4.05) and multiply by 10 to the power of how many decimal places we moved (7). Therefore: 40,500,000 is $4.05 * 10^7$ in scientific notation.
