Need help with solving the following log equation:
3Log(2x) = x-3
I have tried every possible method using log principles, but i am not getting the same answer as that when i use a GDC to look for the intersects. Please help.
the previous response shows a computer generated solution using the Lambert W function.
my advice to you is to get out your calculator and solve it.
graph and look for the real zero.
I cant solve this equation by hand..?! Oh, man... Yes, when i punched it originally into my GDC and looked for the intercept i got x = 6.3 , which checks out when i replace x in the equation. But, i was under the impression it could be solved by hand, apart from taking x/y values and plotting on a graph-paper by hand and looking for the intercepts... How did the Math-Gurus do it 30years ago?? They just graphed it by hand?
