<PRE><B>Question 170841</B>
A) Use scientific notation and the law of exponents to evaluate 
(0.000054)(0.00000033)(0.013)= 5.4x10^-5 * 3.3x10^-7 * 1.3x10^-2
= 2.3166x10^-13
------------------------------------------
. 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) 
Find # of seconds in 10 years:
60*60 = 3.6x10^3 # of seconds in one hour
3.6x10^3*24*365*10*12 = 3.78432x10^9 km/10yrs
