Homework Statement
Determine if the following sets are vector spaces
Part A) R^2; u+v = (u1 + v1, u2 + v2); cu = (cu1,cu2)
part b) M_2,2
A + B = |(a_11 + b_11) (a_12 + b_12)| & cA = |ca_11 ca_12|
|(a_21 + b_21) (a_22 + b_22)| |ca_21 ca_22|
sorry this is a little crude but those are both suppose to be 2X2 matricies
Homework Equations
The Attempt at a Solution
Part A) Yes, it is a vector space because it follows the addition & multiplication properties of vector spaces
Part B) yes it is a vector space because the set is closed under matrix addition & sclar multiplication
Are these statements true and a sufficient answer
