What is the value of x for these functions?

Recommended Posts

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.

Try making the substitution u=e^x. The resulting equation should look familiar to you (maybe bringing back memories of highschool algebra).
