Prove Property
the flig statements
property 1:
one is true by reordering
to form a proof.
A) Assume that A and B are in V
B) Then, Since
Ans
A₁ Bin V = M₂x3, the sum A AB is in V = M₂x5
should
a real number
We then know that A B is a 3x3 matrix of real numbers
the definition AAB, cij = aij x bij
D) By
E
Tot aij, bij, cij be the ijth entries of the matrices
A, B, and C = AⓇB respectively
Therefore, AB must be in V-
be as a
letters-ex FEDCBA-
aij, bij are real numbers, Cij is also
string
