**Reiny**, Monday, March 25, 2013 at 9:20pmln x^4 + ln x = 24 lne

ln (x^5) = 24

5 ln x = 24

ln x = 24/5 = 4.8

x = e^4.8 by definition

x = appr 121.51

yours is not wrong, but you have huge numbers

x^5 = e^24

so x is the fifth root of e^24

or (e^24)^(1/5) = e^4.8

evaluate e^4.8 to get appr 121.51

(really it is the same thing I did )
