Extra Insights

To find the solution to the equation \(\log_{4}\left(\frac{8 x}{x-7}\right)=3\), you correctly set the equation in the exponential form. Therefore, the next step is: \(\frac{8 x}{x-7} = 4^{3}\) Now, with \(4^{3}=64\), you can proceed to solve the equation \(\frac{8 x}{x-7}=64\) for \(x\). Next, adjust the equation to eliminate the fraction: \(8x = 64(x - 7)\) Expanding and then simplifying will lead you to find the value of \(x\). Happy solving!
