## Matrix(algebra): Is A = [1122] equal to B = [1122] ?

Linear spaces and subspaces, linear transformations, bases, etc.

### Matrix(algebra): Is A = [1122] equal to B = [1122] ?

Question 1: A = [1122] and B = [1122]
Find whether the matrices A = B or not.

Check what's the def. of "equal" for matrixes. That will tell you the answer.

Hi,

Actually i got the question like this that

Question 1: A = [1122] and B = [1122]
Find whether the matrices A and matrix B are equal or not.

Okay. Check what's the def. of "equal" for matrixes. That will tell you the answer.

sorry i am re-writting the questions

A= [1122](2*2) and B = [1122](2*2)
Find whether the matrices A ad B are equal ?

I don't know what the scalars are doing behind the matrixes instead of in front of them, but they don't change the definition of "equal" for matrixes. Do the scalar multiplicaition and then Check what's the def. of "equal" for matrixes. That will tell you the answer.
