Create the following matrix: K =

(a) Find Q = K^3 and P = K^T *K.

(b) Report the difference between the sum of second column of K and mean of second row of K.

(c) Replace the third row of K by the sum of the first column and third row. So the 1st item should be K[1, 1] + K[3, 1], 2nd item should be K[2, 1] + K[3, 2], and the 3rd item should be K[3, 1] + K[3, 3]
