Find the value of the determinant |7/3 5/3; 3/2 1/2|
Find the value of the following determinant.
\[\begin{vmatrix} \frac{7}{3} & \frac{5}{3} \\ \frac{3}{2} & \frac{1}{2} \end{vmatrix}\]Find the value of the following determinant.
\[\begin{vmatrix} \frac{7}{3} & \frac{5}{3} \\ \frac{3}{2} & \frac{1}{2} \end{vmatrix}\]Answer: \(-\frac{4}{3}\)
Value of a determinant \(= ad - bc\).
\[= \frac{7}{3}\times\frac{1}{2} - \frac{5}{3}\times\frac{3}{2}\]\[= \frac{7}{6} - \frac{15}{6} = -\frac{8}{6} = -\frac{4}{3}\]Log in or create a free account to answer this question.
