The approach to the first part of this question is to convert each of the logarithmic equations into their respective index equations.

There are two possible approaches to the second part of the question. One approach is to use the first part's results to form two simultaneous equations in a and b to solve for a and b, as I have written them. Another approach is to solve the equations directly before inputting these values of x and y into the logarithmic equations. Remember that x and y have to be positive since the "outputs" cannot be negative.
