\\(x =\\)
Step1: Rewrite 49 as a power of 7
We know that \(49 = 7^2\), so the equation \(7^{\log_{4}(x)} = 49\) can be rewritten as \(7^{\log_{4}(x)} = 7^2\).
Step2: Use the property of exponents
If \(a^m = a^n\), then \(m = n\) (for \(a>0,a
eq1\)). Here, \(a = 7\), so we have \(\log_{4}(x)=2\).
Step3: Convert logarithmic equation to exponential form
The logarithmic equation \(\log_{b}(y)=k\) is equivalent to \(b^k = y\). For \(\log_{4}(x)=2\), we have \(4^2=x\).
Step4: Calculate \(4^2\)
\(4^2 = 16\), so \(x = 16\).
