Vedclass · Answer

(C) આપેલ છે $I = \begin{bmatrix} 1 & 0 & 0 \ 0 & 1 & 0 \ 0 & 0 & 1 \end{bmatrix}$ અને $P = \begin{bmatrix} 1 & 0 & 0 \ 0 & -1 & 0 \ 0 & 0 & -2 \end{bmatrix}$.આપણે $P^2$ અને $P^3$ ની ગણતરી કરીએ:$P^2 = \begin{bmatrix} 1 & 0 & 0 \ 0 & -1 & 0 \ 0 & 0 & -2 \end{bmatrix} \begin{bmatrix} 1 & 0 & 0 \ 0 & -1 & 0 \ 0 & 0 & -2 \end{bmatrix} = \begin{bmatrix} 1 & 0 & 0 \ 0 & 1 & 0 \ 0 & 0 & 4 \end{bmatrix}$.$P^3 = P^2 \cdot P = \begin{bmatrix} 1 & 0 & 0 \ 0 & 1 & 0 \ 0 & 0 & 4 \end{bmatrix} \begin{bmatrix} 1 & 0 & 0 \ 0 & -1 & 0 \ 0 & 0 & -2 \end{bmatrix} = \begin{bmatrix} 1 & 0 & 0 \ 0 & -1 & 0 \ 0 & 0 & -8 \end{bmatrix}$.હવે,$P^3 + 2P^2$ ની ગણતરી કરીએ:$P^3 + 2P^2 = \begin{bmatrix} 1 & 0 & 0 \ 0 & -1 & 0 \ 0 & 0 & -8 \end{bmatrix} + 2 \begin{bmatrix} 1 & 0 & 0 \ 0 & 1 & 0 \ 0 & 0 & 4 \end{bmatrix} = \begin{bmatrix} 1+2 & 0 & 0 \ 0 & -1+2 & 0 \ 0 & 0 & -8+8 \end{bmatrix} = \begin{bmatrix} 3 & 0 & 0 \ 0 & 1 & 0 \ 0 & 0 & 0 \end{bmatrix}$.વિકલ્પો સાથે સરખાવતા,આપણે $2I + P$ ચકાસીએ:$2I + P = 2 \begin{bmatrix} 1 & 0 & 0 \ 0 & 1 & 0 \ 0 & 0 & 1 \end{bmatrix} + \begin{bmatrix} 1 & 0 & 0 \ 0 & -1 & 0 \ 0 & 0 & -2 \end{bmatrix} = \begin{bmatrix} 2+1 & 0 & 0 \ 0 & 2-1 & 0 \ 0 & 0 & 2-2 \end{bmatrix} = \begin{bmatrix} 3 & 0 & 0 \ 0 & 1 & 0 \ 0 & 0 & 0 \end{bmatrix}$.આમ,$P^3 + 2P^2 = 2I + P$ થાય.

જો $I=\begin{bmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{bmatrix}$ અને $P=\begin{bmatrix} 1 & 0 & 0 \\ 0 & -1 & 0 \\ 0 & 0 & -2 \end{bmatrix}$ હોય,તો શ્રેણિક $P^{3}+2P^{2}$ કોના બરાબર થાય?

જો $A=\left[\begin{array}{ccc}2 & 0 & 1 \\ 2 & 1 & 3 \\ 1 & -1 & 0\end{array}\right]$ હોય,તો $A^{2}-5 A+6 I$ શોધો.

આપેલ ગુણાકારની ગણતરી કરો: $\left[\begin{array}{ccc}3 & -1 & 3 \\ -1 & 0 & 2\end{array}\right]\left[\begin{array}{cc}2 & -3 \\ 1 & 0 \\ 3 & 1\end{array}\right]$
