Nanoseconds in a Year

How many nanoseconds are there in one year?

First I found out how many seconds were in a year, then I tried to 
figure how many nanoseconds were in a second.  I know it's simple, but 
I am stuck.

Hi there! Sounds like you're on the right track.  If you know how many 
nanoseconds are in a second and how many seconds are in a year, here's 
what you need to do:

nanoseconds       seconds             nanoseconds
-----------   *   --------    =       ------------  
second             year                 year


Hope this helps!

Thanks for replying so soon, but the problem is I don't know how many 
nanoseconds are in 1 second.  A nanoseconds is 10 to -9 but how do you 
figure out the correct power of ten?

There are "10 to the ninth" nanoseconds in a second.  This is
1000000000 (1 followed by 9 zeroes).  A nanosecond is a very
short amount of time.
