The Hardest Log Question in the World..Watch
Calculate y for which 2log3 y - log3 (y+4) = 2
I expanded and got 2log3 y - ylog3 + 4log3 = 2
But I have no clue what to do next?
Do I do 2 - 4log3 ?
Whats with the sudden influx of log questions all of a sudden o_O
I think the log questions in the actual C2 exams are rather easy though.
The mixed exercise in edexcel for logs is quite hard too.
