Ineed this badlywrite each numeral in scientific notation 6,282

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.

Taking off 10% of £680;

10% of 680 =

0.1*680=68

Therefore:

680-68=612.

The answer is 612. HOPE THIS HELPS
