dcowboys107 Posted October 5, 2009 Share Posted October 5, 2009 What is the value of x for these equations? a. Find all solutions for this equation: (e^2x)-(6e^x)+32/4=0 b.(e^x)-24e^(-x)=-2 Use common logs to solve for x in terms of y for the following: c.y=10^x+10^(-x) ----------------- 18 I don't know even where to start. . . I'd apprecite all the help possible. Link to comment Share on other sites More sharing options...
NeonBlack Posted October 5, 2009 Share Posted October 5, 2009 Try making the substitution u=e^x. The resulting equation should look familiar to you (maybe bringing back memories of highschool algebra). Link to comment Share on other sites More sharing options...
