જો ${x^a}{y^b} = {e^m},{x^c}{y^d} = {e^n},{\Delta _1} = \left| {\,\begin{array}{*{20}{c}}m&b\\n&d\end{array}\,} \right|\,\,{\Delta _2} = \left| {\,\begin{array}{*{20}{c}}a&m\\c&n\end{array}\,} \right|$ અને ${\Delta _3} = \left| {\,\begin{array}{*{20}{c}}a&b\\c&d\end{array}\,} \right|$, તો $x$ અને $y$ ની કિમત મેળવો.

• A

  ${\Delta _1}/{\Delta _3}$ અને ${\Delta _2}/{\Delta _3}$

• B

  ${\Delta _2}/{\Delta _1}$ અને ${\Delta _3}/{\Delta _1}$

• C

  $log$ $({\Delta _1}/{\Delta _3})$ અને $log$ $({\Delta _2}/{\Delta _3})$

• D

  ${e^{{\Delta _1}/{\Delta _3}}}$ અને ${e^{{\Delta _2}/{\Delta _3}}}$
