Solve for $17^{x}$ if $\log _{3}\left((-26)+17^{x}\right)=3$.
\[
17^{x}=
\]
Finally, we simplify to get \(17^{x}=\boxed{53}\).
Step 1 :First, we rewrite the equation using the property of logarithms, which states that \(\log _{b} a^{n}=n \log _{b} a\). So, we have \(\log _{3}(-26+17^{x})=3\).
Step 2 :Next, we convert the logarithmic equation to an exponential equation. This gives us \(3^{3}=-26+17^{x}\).
Step 3 :Solving for \(17^{x}\), we get \(17^{x}=3^{3}+26\).
Step 4 :Substituting the values, we get \(17^{x}=27+26\).
Step 5 :Finally, we simplify to get \(17^{x}=\boxed{53}\).
