Q. Which of the following is equivalent to \newlinelogc(6)log(6)\frac{\log_{c}(6)}{\log(6)} ?\newlineChoose 11 answer:\newline(A) log(c)\log(c)\newline(B) logc(1)\log_{c}(1)\newline(C) 1log(c)\frac{1}{\log(c)}\newline(D) 1log(6)\frac{1}{\log(6)}
  1. Apply Change of Base Formula: We can use the change of base formula for logarithms, which states that loga(b)=logc(b)logc(a)\log_{a}(b) = \frac{\log_{c}(b)}{\log_{c}(a)} for any positive numbers aa, bb, and cc (where a1a \neq 1 and c1c \neq 1). We can apply this formula to the given expression by choosing a new base for the logarithm.
  2. Rewrite Expression: Let's rewrite the given expression using the change of base formula. We have:\newlinelogc(6)log(6)=logc(6)logc(c)\frac{\log_{c}(6)}{\log(6)} = \frac{\log_{c}(6)}{\log_{c}(c)}\newlineSince logc(c)=1\log_{c}(c) = 1 (because any number to the power of 00 is 11), the expression simplifies to:\newlinelogc(6)1=logc(6)\frac{\log_{c}(6)}{1} = \log_{c}(6)
  3. Simplify Expression: Now, we need to match our simplified expression to one of the given answer choices. The expression logc(6)\log_{c}(6) does not match any of the choices directly, but we can look for a property that might help us further simplify or transform the expression.
  4. Eliminate Number 66: We notice that none of the answer choices contain the number 66, so we must find a way to eliminate it from our expression. We can use the fact that logc(1)=0\log_{c}(1) = 0 for any base cc (since any number to the power of 00 is 11). However, this does not help us directly with our current expression logc(6)\log_{c}(6).
  5. Revisit Change of Base Formula: We can now see that the expression logc(6)\log_{c}(6) cannot be simplified further to match any of the given answer choices. However, we can revisit the change of base formula and apply it in a different way:\newlinelogc(6)log(6)=1log(6)/logc(6)=1log6(c)\frac{\log_{c}(6)}{\log(6)} = \frac{1}{\log(6) / \log_{c}(6)} = \frac{1}{\log_{6}(c)}\newlineThis matches one of the answer choices.
  6. Match Answer Choice: The correct answer choice that matches our final expression 1log6(c)\frac{1}{\log_{6}(c)} is:\newline(C) 1log(c)\frac{1}{\log(c)}\newlineThis is because the change of base formula allows us to write the denominator log(6)log(c)\frac{\log(6)}{\log(c)} as log6(c)\log_{6}(c), and taking the reciprocal gives us 1log6(c)\frac{1}{\log_{6}(c)}.
