Find DE if matrix D= Row 1= 2,4,6 and ROW 2= 5,7,1 and matrix E= Row 1= 1,2
Row 2= 0,4, and Row 3= 3,4
WORK: [(2)(1)+(4)(0)+(6)(3)]=20
[(2)(2)+(4)(4)+(6)(4)]=44
[(5)(1)+(7)(0)+(1)(3)]=2
[(5)(2)+(7)(4)+(1)(4)]=34
The answers to choose from are:
A) Row 1= 20, 44 and Row 2= 8, 42
B) Row 1= 20, 8 and Row 2= 44, 42
I don't know where I am going wrong. Hopefully you can spot my error!!
Thanks.
