Q. Expand the logarithm fully using the properties of logs. Express the final answer in terms of logx,logy \log x, \log y , and logz \log z .\newlinelogyz4x2 \log \frac{\sqrt{y} z^{4}}{x^{2}} \newlineAnswer:
  1. Apply Quotient Rule: Let's start by applying the quotient rule of logarithms, which states that log(ab)=log(a)log(b)\log(\frac{a}{b}) = \log(a) - \log(b). So, we have log(yz4x2)=log(yz4)log(x2)\log\left(\frac{\sqrt{yz^{4}}}{x^{2}}\right) = \log(\sqrt{yz^{4}}) - \log(x^{2}).
  2. Deal with First Term: Now, let's deal with the first term, log(yz4)\log(\sqrt{yz^{4}}). The square root is the same as raising to the power of 12\frac{1}{2}, so we can rewrite this as log((yz4)12)\log((yz^{4})^{\frac{1}{2}}).\newlineUsing the power rule of logarithms, which states that log(an)=nlog(a)\log(a^{n}) = n\log(a), we get log((yz4)12)=(12)log(yz4)\log((yz^{4})^{\frac{1}{2}}) = (\frac{1}{2})\log(yz^{4}).
  3. Apply Product Rule: Next, we apply the product rule of logarithms to the term log(yz4)\log(yz^{4}), which states that log(ab)=log(a)+log(b)\log(ab) = \log(a) + \log(b). This gives us (12)(log(y)+log(z4))(\frac{1}{2})\cdot(\log(y) + \log(z^{4})).
  4. Apply Power Rule: Now, let's apply the power rule again to log(z4)\log(z^{4}), which gives us log(z4)=4log(z)\log(z^{4}) = 4\log(z). So, we have (12)(log(y)+4log(z))(\frac{1}{2})\cdot(\log(y) + 4\log(z)).
  5. Distribute Coefficients: We can distribute the 12\frac{1}{2} to both terms inside the parenthesis, resulting in (12)log(y)+(12)4log(z)(\frac{1}{2})\log(y) + (\frac{1}{2})\cdot 4\log(z), which simplifies to (12)log(y)+2log(z)(\frac{1}{2})\log(y) + 2\log(z).
  6. Address Second Term: Now, let's address the second term from step 11, log(x2)\log(x^{2}). Applying the power rule of logarithms, we get log(x2)=2log(x)\log(x^{2}) = 2\cdot\log(x).
  7. Combine All Terms: Finally, we combine all the terms together to get the expanded form of the original logarithm.\newlineWe have log(yz4)log(x2)\log(\sqrt{yz^{4}}) - \log(x^{2}) which becomes (12)log(y)+2log(z)2log(x)(\frac{1}{2})\log(y) + 2\log(z) - 2\log(x).
