Vedclass · Answer

(A) આપેલ શ્રેણિકો $A=\left[\begin{array}{cc}i & 0 \ 0 & -i\end{array}ight]$,$B=\left[\begin{array}{cc}0 & -1 \ 1 & 0\end{array}ight]$,અને $C=\left[\begin{array}{cc}0 & i \ i & 0\end{array}ight]$ છે.શ્રેણિકોના વર્ગની ગણતરી કરતા:$A^2 = \left[\begin{array}{cc}i & 0 \ 0 & -i\end{array}ight] \left[\begin{array}{cc}i & 0 \ 0 & -i\end{array}ight] = \left[\begin{array}{cc}i^2 & 0 \ 0 & (-i)^2\end{array}ight] = \left[\begin{array}{cc}-1 & 0 \ 0 & -1\end{array}ight] = -I$.$B^2 = \left[\begin{array}{cc}0 & -1 \ 1 & 0\end{array}ight] \left[\begin{array}{cc}0 & -1 \ 1 & 0\end{array}ight] = \left[\begin{array}{cc}-1 & 0 \ 0 & -1\end{array}ight] = -I$.$C^2 = \left[\begin{array}{cc}0 & i \ i & 0\end{array}ight] \left[\begin{array}{cc}0 & i \ i & 0\end{array}ight] = \left[\begin{array}{cc}i^2 & 0 \ 0 & i^2\end{array}ight] = \left[\begin{array}{cc}-1 & 0 \ 0 & -1\end{array}ight] = -I$.વર્ગોનો સરવાળો:$A^2+B^2+C^2 = (-I) + (-I) + (-I) = -3I = \left[\begin{array}{cc}-3 & 0 \ 0 & -3\end{array}ight]$.હવે,$3 A^2 B^2 C^2$ ની ગણતરી કરતા:$3 A^2 B^2 C^2 = 3(-I)(-I)(-I) = 3(-I)^3 = 3(-I) = -3I$.આમ,$A^2+B^2+C^2 = -3I$ અને $3 A^2 B^2 C^2 = -3I$ હોવાથી,આપણે કહી શકીએ કે $A^2+B^2+C^2 = 3 A^2 B^2 C^2$.

જો $A=\left[\begin{array}{cc}i & 0 \\ 0 & -i\end{array}\right]$,$B=\left[\begin{array}{cc}0 & -1 \\ 1 & 0\end{array}\right]$ અને $C=\left[\begin{array}{cc}0 & i \\ i & 0\end{array}\right]$ હોય,તો નીચેનામાંથી કયું સાચું છે?
