1. ## 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... ?
