Question 153692: 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)

(0.000054)(0.00000033)(0.013)
5.4+%2A+10%5E%28-5%29+%2A+3.3+%2A+10%5E%28-7%29+%2A+1.3+%2A+10%5E%28-2%29
Add the exponents and multiply the other numbers
5.4+%2A+3.3+%2A+1.3+%2A+10%5E%28-5+-+7+-+2%29
23.166+%2A+10%5E%28-14%29
Now put the 23.166 in scientific notation
2.3166+%2A+10%5E1+%2A+10%5E%28-14%29
2.3166+%2A+10%5E%28-13%29 answer
