6,282, written in scientific notation, would be:
6.282 x 10^3
Yo find this, take the original number, 6,282, and move the decimal to the left three spaces, until the number is less than 10.
You end up with 6.282. The 10^3 part comes from the number of spaces you moved the decimals. You moved it three spaces, therefore, 3 is the exponent.
