Step 1 :Calculate the definite integral of the function \(f(x)=\frac{8}{x}\) from \(x=6\) to \(x=12\)
Step 2 :Use the formula for the definite integral of \(f(x)=\frac{8}{x}\) to find the area under the curve
Step 3 :Compute the integral to get \(-8\log(6) + 8\log(12)\)
Step 4 :Simplify the expression using logarithm properties
Step 5 :Final Answer: \(\boxed{-8\log(6) + 8\log(12)}\)
