Question 55

Multiple Choice

Find the inverse of the matrix A, if it exists.
- A=[108123253]A = \left[ \begin{array} { l l l } 1 & 0 & 8 \\1 & 2 & 3 \\2 & 5 & 3\end{array} \right]


A) A1=[108123253]A ^ { - 1 } = \left[ \begin{array} { r r r } - 1 & 0 & - 8 \\ - 1 & - 2 & - 3 \\ - 2 & - 5 & - 3 \end{array} \right]
B) A1\mathrm { A } ^ { - 1 } does not exist.
C) A1=[940163135152]A ^ { - 1 } = \left[ \begin{array} { r r r } 9 & - 40 & 16 \\ - 3 & 13 & - 5 \\ - 1 & 5 & - 2 \end{array} \right]
D) A1=[112025833]\mathrm { A } ^ { - 1 } = \left[ \begin{array} { l l l } 1 & 1 & 2 \\ 0 & 2 & 5 \\ 8 & 3 & 3 \end{array} \right]
