An exponent is how many times to use the number in a multiplication. Therefore, 10 to the 8th power is 100,000,000. It is solved by the equation 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10
Calculate powers of 10 using a shortcut: add the same number of zeros as the exponent to the number 1. For example, to calculate 10 to the 8th power quickly, place 8 zeros after the 1. To determine where the commas go after calculating the power of 10, start at the end of the number with the last zero. Count back three digits at a time and insert a comma. Continue this until the beginning of the number is reached.
