Hi smmmc!

Just using the rules leads to Do you see which rule I used in each step? Did you understand everything? well, you know how to calculate it, right? Regards Rapha
You are being asked to apply the rules: , and . Apply these rules to the given expression, make the substitutions they give you, and simplify where necessary. EDIT: Too slow!

I would first rewrite the fraction as a sum/difference of logs: Can you take it from here? 01 EDIT: Ack, beaten to it by three posters!
Hey thank you all ! Thanks for providing me hints and directing me to the right way
