Question

Help! I need help with this worksheet :( I have no idea how to do it :( http://tinypic.com/view.php?pic=35k4mmo&s=6

Answer 1

huh? I don't understand

Answer 2

which one do you want to do?

Answer 3

the first couple are going to be easier if you simplify the expressions using the properties of the log

Answer 4

for example
\[\ln(\frac{5x^3}{x^2-5})^3=3\ln(\frac{5x^3}{x^2-5})\]
\[=3\left(\ln(5x^3)-\ln(x^2-5)\right)=6\ln(5x)-3\ln(x^2-5)\]\[=6\ln(5)+6\ln(x)-3\ln(x^2-5)\]

Answer 5

actually that is wrong, it is \[3\ln(5)+6\ln(x)-3\ln(x^2-5)\] but it doesn't really matter because the derivative of the constant is 0

Answer 6

ohh okay, and I was needing help on all of them
