Q126
For given matrix \[ P = [ array*20c 4 + 3 i& - i \\ i&4 - 3 i array ]\] where \[ i = - 1 ,\] the inverse of matrix P is
For given matrix {\text{P}} = \left[ {\begin{array}{*{20}{c}}
{4 + 3{\text{i}}}&{ - {\text{i}}} \\
{\text{i}}&{4 - 3{\text{i}}}
\end{array}} \right] where the inverse of matrix P is
A.
\frac{1}{{24}}\left[ {\begin{array}{*{20}{c}}
{4 - 3{\text{i}}}&{\text{i}} \\
{ - {\text{i}}}&{4 + 3{\text{i}}}
\end{array}} \right]
AnswerB.
\frac{1}{{25}}\left[ {\begin{array}{*{20}{c}}
{\text{i}}&{4 - {\text{i}}} \\
{4 + 3{\text{i}}}&{ - {\text{i}}}
\end{array}} \right]
C.
\frac{1}{{24}}\left[ {\begin{array}{*{20}{c}}
{4 + 3{\text{i}}}&{ - {\text{i}}} \\
{\text{i}}&{4 - 3{\text{i}}}
\end{array}} \right]
D.
\frac{1}{{25}}\left[ {\begin{array}{*{20}{c}}
{4 + 3{\text{i}}}&{ - {\text{i}}} \\
{\text{i}}&{4 - 3{\text{i}}}
\end{array}} \right]
