Caitlyn grade 11 precalculus problem: ln x + ln (x2) = 1 I can solve this on the calculator, but the book wants 1+ [(sqroot)1+e]. How can I get the e? OR problem: ln x + ln (x^2 + 1) = 8 

Hi Caitlyn, You need to use the property of the log function that is
Hence ln x + ln (x2) = 1 becomes
Now raise both sides to the power of e to get
This you can solve using the general quadratic. Penny
