text: # Why is $log(n)+log(\frac{n}{2})+log(\frac{n}{4})+log(\frac{n}{8})+log(\frac{n}{16})+…+log(\frac{n}{n})=\Theta (log^2(n)$
  
  $$log(n)+log(\frac{n}{2})+log(\frac{n}{4})+log(\frac{n}{8})+log(\frac{n}{16})+…+log(\frac{n}{n})=\Theta (log^2(n)$$
  
  The sum of logarithms is the logarithm of the product $$n*\frac{n}{2}*\frac{n}{4}*\frac{n}{8}*\frac{n}{16}*…*\frac{n}{n}$$. This equals $$n^{log(n)}$$ divided by what? If the product would just be $$n^{log(n)}$$, then this would make perfect sende since $$log(n^{log(n)})=log(n)*log(n)=log^2(n)$$. But the divisor equals $$\frac{1}{2}*\frac{1}{4}*\frac{1}{8}*\frac{1}{16}*…*\frac{1}{n}$$ so I don’t get it.
explanation: The text extract contains a detailed mathematical question about the evaluation of a logarithmic series and its relationship to the big-theta notation. The user is asking for an explanation of why the given series equals \(\Theta(\log^2(n))\). The extract also includes a partial attempt at solving the problem, but it does not provide a complete answer.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
