Question 199490
<font face="Garamond" size="+2">


If you think because you were asked for the identifying information for your textbook that we have access to your book, you are mistaken.  In general, we don't have your textbook available.  Think about it for a minute:  1000+ mathematics textbooks out there at $50 to $250 bucks each, and we are all unpaid volunteers.  The textbook identification information is so that the website can improve the ability of students to find problems that have been previously solved.


You have to post the problem with which you are having difficulty.  One problem per post, please.  And <b><i>show your work so far</i></b>.
