how to solve the equation 2^x=5x using logs? note this is an exponetial equation,not a quadratic.

not possible, this is similar to saying, solve 2x=3x.

It is possible but there is no method in junior cert maths that you can use to solve this. You are probably expected to use a graph to estimate the solution

Chris241197
Show me how it possible then, or don't say it JackW ( This may be coming across as rude but I genuinely want to know this method not on the junior cert).

YOU CANNOT MAKE X THE SUBJECT OF THIS EQUATION WITH NO OTHER VARIABLE
