An instructional video explaining what happens to the determinant when one row in a matrix is multiplied by a scalar. Proves that the new determinant will simply be the scalar times the original determinant. Also addresses the case when all rows of a matrix are multiplied by a scalar. Shows that the determinant will then be the scalar raised to the power equal to the number of rows in the matrix times the original determinant. [13:20]
