(3) Problem 3. Please provide a typewritten solution! I will be very grateful!. 
Please Solve only (a) and b(iv) 

Problem 3. (a) Let A be an m x n matric. Define what is meant by the null space of A, N(A). Prove that N{A) is a subspace of R". (b) Let c1, c2, Cz denote the columns of the matrix 1 -7 5 -8 16 A - -1 5 -1 2 -3 -12 (i) Find rank(A). (ії) Find a basis for N(A). (iii) Find a basis for the range of A, R(A). (iv) Let d = c1+c2+C3. Before attempting to solve the system, erplain why you know that Ax solution of the system of equations Ax = d. d is consistent. Write down a general
