Q:
7. One common use of positive and negative exponents is in writing numbers as scientific notation. For example 0.000052 can be written as 5.2 10-5. A) Use scientific notation and the laws of exponents to evaluate (0.000054)(0.00000033)(0.013). Leave your answer in scientific notation. B) If a space probe travels at 12 kilometers per second for 10 years, how far will it travel? Write your answer in scientific notation. (Assume 1 year = 365 days)

Scientific Notation: A number is expressed in scientific notation when it is in the form a x 10n, where a is greater than or equal to 1 but less than 10 and n is an integer.
