Answer
$8.71 \times 10^{-2}\ oz$
Work Step by Step
Using our knowledge of units, we find:
$ 24.7 \times 3.52 \times 10^{-3} oz$
To convert to scientific notation, move the decimal to the right or left, counting the number of times that you do so, until you get a number that is at least 1 but that is less than 10. If you moved the decimal right, the number of times the decimal is moved will be negative, while moving left yields a positive number. Then, raise 10 to that number. This gives:
$8.71 \times 10^{-2}\ oz$
