Step 1 :Assume y to be a positive number
Step 2 :Calculate the logarithms: \(\log(8) = 2.0794415416798357\), \(\log(y) = 0.0\), \(\log(7) = 1.9459101490553132\)
Step 3 :Calculate the final expression: \(2.0794415416798357 + 0.0 - 1.9459101490553132 = 0.13353139262452252\)
Step 4 :The numerical value of the expression when y is assumed to be 1 is approximately 0.1335
Step 5 :The final answer is the expression we derived earlier: \(\log(8) + \log(y) - \log(7)\)
Step 6 :Final Answer: \(\boxed{\log(8) + \log(y) - \log(7)}\)
