જો $A=\left[\begin{array}{cc}1 & 5 \\ \lambda & 10\end{array}\right], A ^{-1}=\alpha A +\beta I$ અને $\alpha+\beta=-2$ હોય, તો $4 \alpha^2+\beta^2+\lambda^2=.......$
જો $A = \left[ {\begin{array}{*{20}{c}}1&{ - 1}&1\\0&2&{ - 3}\\2&1&0\end{array}} \right]$ અને $B = (\text{adj}\,A)$, અને $C = 5A,$ તો $\frac{{|\text{adj}B|}}{{|C|}}=$
