/sci/ I beg of you for help. I spent my whole evening trying to figure this out...maybe I'm a square head. Honestly, I know it's somtehing with logarithms...but I have no idea how to solve it. Really I used a lot of papers...can anyone please help me?
>>7790669 misread your 2 as a 4, but he's right.
x=0 is the only solution. To see this, try graphing both the left side (which is concave up with a minimum at x=0) and the right side (which is concave down with a maximum at x=0). So the two graphs can intersect at only the point (0,2), so the only solution is x=0.
