You have a notation error in indicating that these are 1 sum. Each set of parentheses are a sum over 1 index and summing the parentheses gives the double sum.

For (d) you have already correctly calculated $\displaystyle \overline{L}$ so you can construct the new matrix by subtracting $\displaystyle \overline{L}$ from each
number in the given matrix and squaring. Now find the sum as before
