My process must be off or something because I keep getting x=18. $\displaystyle \frac 12 \log (x + 2) + \log 5 = 1$ $\displaystyle \Rightarrow \log \sqrt{x + 2} + \log 5 = 1$ $\displaystyle \Rightarrow \log (5 \sqrt{x + 2}) = 1$ now continue
wow thanks that was extremely easy. don't know what i was doing wrong b4 that.
