    Exponents and Logs

    If the point (3,10) is on the graph of y=a^x, then what is the point on the graph of y=logax a is the base, not sure how to make it look that way.
    How do i do this, i get an answer of 1.12 and -1.12

    y = \log_a{x} is the inverse function of y = a^x.

    So the x and y values swap.
