    oh, wow, thanks!!! so, basically, whenever i need to find the derivative of a power logarithmic function, i first apply the logarthmic properties as to get rid of the exponent, right?

    yes, thanks. it's easier when they give the symbols. I was guessing. I didnt know i could just type "differentiate". can i type "integrate" too?
