Question 1084449
1 5
2 6
:
this is a 2 by 2 matrix, that is 2 rows by 2 columns
:
(1/2) * R2 = (1, 3)
:
this is a 1 by 2 matrix, that is, 1 row by 2 columns
:
it is not possible to multiply these two matrices
:
for this to work (1,3) would have to be 2 rows by 1 column
:
if I assume this is what you mean, then
:
1 5
2 6
:
multiplied by (1,3) is (1+15, 2+18) = (16, 20)
:
then your matrix becomes
:
1 5
16 20
:
