Question
Write each expression as a single logarithm with coefficient I. Assume all variablesrepresent positive real numbers, with a ~ I and b ~ 1.$$5 \log _{a}(z+7)+\log _{a}(2 z+9)$$
Step 1
The power rule states that $n \log_a b = \log_a (b^n)$. So, the given expression becomes: $$ \log _{a}((z+7)^5)+\log _{a}(2 z+9) $$ Show more…
