Given that matrix

B = {\begin{cases} \sqrt{3} \\ - \sqrt{5} \end{cases} \begin{matrix} \sqrt{2} \\ \sqrt{7} \end{matrix}} find

B^{- 1} using row operation

d e t (B) = \sqrt{21} + \sqrt{10}

B^{- 1} = \frac{1}{\sqrt{21} + \sqrt{10}} (\begin{matrix} \sqrt{7} - \sqrt{2} \\ \sqrt{5} \sqrt{3} \end{matrix})
