Write Matrix Determinant: Write down the matrix to find its determinant.The matrix is:[0amp;71amp;0]
Use Determinant Formula: Use the formula for the determinant of a 2×2 matrix.The determinant of a 2×2 matrix [aamp;bcamp;d] is ad−bc.For our matrix, a=0, b=7, c=1, and d=0.
Calculate Determinant: Calculate the determinant using the values from the matrix.Determinant = (0×0)−(7×1)Determinant = 0−7Determinant = −7
