(a) the set r2 with the following addition and scalar multiplication operations on u = (u1,2) e r2 and v = (v1, 2) r2 (u11 u221 (ки, киз). ku u v= (b) the set p of all rcal-valucd polynomials (i. c. with real cocfficients) of degrcc less to n, and with standard polynomial operations of addition and scalar equa than or multiplication (c) check the axiom 6 for each of (a) and (b) with k complex, and conclude whether any of these sets is a complex vector space?
