Determine the point of intersection between: $\displaystyle y = 5(4)^(2X)$ $\displaystyle y = 4(2)^(6X)$ I believe that I can change the first equation to $\displaystyle y = 5(2)^(4X) $ but am stuck after that.

Hello, Originally Posted by Yale Determine the point of intersection between: $\displaystyle y = 5(4)^(2X)$ $\displaystyle y = 4(2)^(6X)$ I believe that I can change the first equation to $\displaystyle y = 5(2)^(4X) $ but am stuck after that. $\displaystyle 5 \cdot 2^{4X}=4 \cdot 2^{6X}=2^2 \cdot 2^{6X}=2^{6X+2}$ ---> $\displaystyle 5=\frac{2^{6X+2}}{2^{4X}}=2^{2X+2}$ Take the logarithms... ?
