A 48-year-old person is 4.2048 × 105 hours old. Write this number in standard form.

1 answer:

6 0

4.2048 x 105 = 441.504

the standard form should be between 1 and 9 so the decimal point should be after the first digit (4)

it would look like this 4.41504 x 10 to the power of 2 because it moved back two places. hope it makes sense? (:
