Question 154072: 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 „e 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) Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! A) Use scientific notation and the laws of exponents to evaluate (0.000054)(0.00000033)(0.013). Leave your answer in scientific notation.
--------------
(0.000054)(0.00000033)(0.013) = (5.4E-5)*(3.3E-7)*(1.3E-2)
= 23.166E-14
=2.3166E-15
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)
----------------
60 sec per min
60 min per hour
24 hr per day
365 day per year
12*60*60*24*365*10 = 3784320000 km
= 3.78432E8 km, or
= 3.78432*10^8 km
