If so, can you tell me how to do it. 3+8 ln x=8 Click to expand... Let's get ln x by itself on one side. 3 - 3 + 8 ln x = 8 - 3 8 ln x = 5 Now, divide both sides of the equation by 8: (8 ln x) / 8 = 5/8 ln x = 5/8 You can now change this to exponential notation. The base for ln is e.... if ln x = 5/8, then x = e^(5/8) Calculator time....
