The product of any matrix by the scalar________ is the : matrix.
Let $A$ be any matrix and $k$ is any scalar. The matrix obtained by multiplying every element of matrix $A$ by $k$ is called the scalar multiplication of matrix $A$ by $k$. It is denoted by $k A$.
It is given that,
We know that, a matrix whose all elements are zero is called a : matrix.
Here, $A$ is any matrix. So, when all the element of the matrix $A$ are multiplied by 0 , we will get a matrix whose all elements are zero i.e. a : matrix. Thus, the product of any matrix by the scalar o gives a : matrix.
The product of any matrix by the scalar 0 is the : matrix.
