Hi goosey00,How do you divide using ln:
my example is x(7ln5-ln3)=-2ln5 and divide 7ln5-ln3 by both side to get x. So I have -2ln5/7ln5-ln3 and I can't seem to find the answer.
ln(-2) is impossible first of all The log and natural log aren't defined for 0 or negative numbers. This also depends on what kind of calculator you have. Hopefully you can enter in long expressions before hitting "equals". If so you should type something like:Its not multiple choice, they want me to divide and when I enter it in my calculator, I must be entering it wrong. I am entering ln(-2)5/ln(7)5-ln(3). Please don't laugh, I just am clueless.
What do you mean off by 2 decimal places? It was plus or minus .01 from my answer? What kind of calculator do you have again?I couldn't do the long way on the calculator. I think I can just break it down but to get your answer I was off 2 decimal places. Is that normal?
