  1. Given that \(\log_a y = 2\log_a 7 + \log_a 4 + \frac{1}{2}\), find \(y\) in terms of \(a\). [4 marks]
  2. When asked to solve the equation $$2\log_a x = \log_a 9 - \log_a 4$$ a student gives the following solution: \(2\log_a x = \log_a 9 - \log_a 4\) \(\Rightarrow 2\log_a x = \log_a \frac{9}{4}\) \(\Rightarrow \log_a x^2 = \log_a \frac{9}{4}\) \(\Rightarrow x^2 = \frac{9}{4}\) \(\therefore x = \frac{3}{2}\) or \(-\frac{3}{2}\) Explain what is wrong with the student's solution.
