\(\frac{2x+3}{log_4x}>0\\ log_4x\qquad \text{Is positive when x>1}\\ if\;\;x>1\quad then\\ 2x+3>0\\ 2x>-3\\ x>-3/2\\ \text {So positive when x>1 }\)
\(\frac{2x+3}{log_4x}>0\\ log_4x\qquad \text{Is negative when 0<x<1}\\ if\;\; 0<x<1\quad then\\ 2x+3<0\\ 2x<-3\\ x<-3/2\\ \text {No solution here. }\)
So the domain of the solution is \(x>1\)
