i need help with this one question; we have to write ln9-3ln(squareroot 3) + ln81 in the form kln3 where k is an exact fraction; i dont remember how to do this at all so any help would be greatly appreciated; thanks
Remember that taking the square root is the same as raising to the 1/2 power. You may also want to combine the logs before making the exponents into the coefficients. Do you remember your log properties?
A good advice:
When doing maths you are not too familiar with, keep the definitions right in front of you while you're working, until you don't need to look at them anymore.
yeah, that is good advice; it's just that that was a review question from my calculus textbook, stuff that we learned in highschool and haven't seen in some time; we were just expected to remember how to do it and i forgot; well, thanks for all your help
