I've been having problems w/ the equation: "log base x of 3 + log base x of 5 = x." I can use a property of logs to get: "log base x of 15 = x." I can change forms into exponential to get: "x^x = 15." I've tried many different things from here, but nothing seems to definately work. I can use my graphing calculator to get an approximate of x = 2.713... but I wonder if I can somehow get an exact answer because I'm weird. Thanks if you can help.
