Despite the kind explanations in the answer sheet, I am not sure how to calculate the part (a) of the 4th exercise.

Could you let me know some more detail?

The likelihood of the parameters is

L(\mu,\sigma^2) = \prod_{j=1}^n p(y_j|\mu,\sigma^2) = \prod_{j=1}^n (2 \pi \sigma^2)^{-1/2} \exp(-(y_j - \mu)^2/(2 \sigma^2)). The result follows by taking the log of this expression.
