Hi, I've hit a brick wall here...not sure how to proceed Some insight on the original function: ln(x)=log4(x+3)log4(x2) Now solve for Ln(1/2) therefore.... Ln(1/2)= Log4(1/2+3)Log4(1/22) = Log4((7/2)/(3/2)) = Log4(7/3)....now what? i know i have to apply the natural log at this point, but why? how? i don't understand...HELP!!!
