Now over here we've been given two matrices.
00:04
The matrix a is given to us as 7 .5 minus 4 minus 2, 5, 1, 10 minus 4 minus 7.
00:17
See i'm just noting down the elements only.
00:20
And matrix b is given to us as it is a 3 by 3 order matrix or i can say it is a square matrix.
00:27
Okay, 8 1, 4 minus 4.
00:31
Form 2 and minus 8 like this.
00:34
Okay, we are supposed to find out the matrix a b.
00:38
So for that, let us check whether we can multiply these two matrices or not.
00:43
So for that, what we need to first check is, let's check the order first.
00:47
So matrix a is of the order 3 by 3, whereas the second one is also of the order 3 by 3...
