dcowboys107 Posted October 2, 2009 Share Posted October 2, 2009 a.ln(x)-ln(6-x)=3 b.log base 2 of (x+5)=log base 2 of (x-5)+log base 6 of (36)+6^(log base 6 of 3) a.ln(x) - ln(6-x) = 3 ln(x/(6-x)) = 3 x/(6-x) = e³ I've gotten this far for part a but now I can't solve for x. log[base 2] ((x+5)/(x-5)) = 2 + 3 (x+5)/(x-5) = 2^5 Part b I've gotten this far. It says not to give a decimal approximation for any of the problems rather a fraction or an exact expression. Can someone show me how to solve for x in these two problems? Thanks!

timo Posted October 2, 2009 Share Posted October 2, 2009 Multiply with the denominator, (then) solve as normal. Link to comment Share on other sites More sharing options...
