 Question 39095: Hi, please help me on this question, I've been thinking about it for a long time. If and , determine a) the values of x and y in terms of a, using positive indices. b) an equation of x in terms of y I've tried using the first log rule to do both equations and came up with and resectively but I don't know where to go from there. I also transformed it into an exponential equation and respectively and still have no clue of what to do. Thank you. Click here to see answer by AnlytcPhil(1276)
