<PRE><B>Question 192723</B>
 A) Use scientific notation and the laws of exponents to evaluate (0.000048)(0.0000035)(0.00014). Leave your answer in scientific notation. 
(4.8x10^-5)(3.5x10^-6)(1.4x10^-4) = 2.352x10^-14
-----------------------------------------------------------

B) If a space probe travels at 100 kilometers per second for 12 years, how far will it travel? Write your answer in scientific notation. (Assume 1 year = 365 days) 
-------------------
seconds in 12 years: 12*365*24*60*60 = 3.784x10^8
----------
distance covered at 100 km per sec. = 3.784x10^10
