    The circumference of the Earth is approximately 131,000,000 ft. a. Write this number in scientific notation and tell how you knew whether to use a positive or a negative exponent. b. The circumference of Mars is 7.00 x 107. Which planet is larger, and by how many feet? Write the answer in both standard and scientific notation.
