rue or False 1. Matrices are often represented by single small letters a, b, c... etc. 2. Two m x n matrices A and B are equal if aij=bij for each i & j. (i.e., the two matrices have same size, and all the corresponding elements are equal). 3. Matrices A & B are said to be conformable in the order AB if, and only if, the number of rows in A is equal to the number of columns in B. 4. Suppose Matrix A is having 4 rows and 3 columns, and Matrix B is having 3 rows and 2 columns. The product size of AB is a 4 x 2 matrix. 5. Suppose B is the matrix obtained from an n x n matrix A by multiplying the entries in a row/column by a non-zero constant and adding the result to the corresponding entries in another row/column. Then, det(B) = det(A).
