Let a = (1 1 2 0 3 2) and b = (-1 1 5 1 -2 -1) find a + b. 3b, -2b, a + 2b, 2a + b, a - b, a - 2b, b - a. let a = (1 2 -1 1) and b = (-1 0 1 -3) find a + b, 3b, -2b, a + 2b, a - b, b - a. (a) write down the row vectors and column vectors of the matrices a, b in exercise 1. (b) write down the row vectors and column vectors of the matrices ay b in exercise 2. (a) in exercise i, find 'a and 'b. in exercise 2, find ^t a and ^tb. if a, b are arbitrary m times n matrices, show that ^t(a + b) = ^t a + ^t b.
