    Log Functions Help

    Determine the point of intersection between:
     y = 5(4)^(2X)
     y = 4(2)^(6X)

    I believe that I can change the first equation to y = 5(2)^(4X) but am stuck after that.

    5 \cdot 2^{4X}=4 \cdot 2^{6X}=2^2 \cdot 2^{6X}=2^{6X+2}

    ---> 5=\frac{2^{6X+2}}{2^{4X}}=2^{2X+2}

    Take the logarithms... ?
