Mathematics - Determinant Question with Solution | TestHub

Let$\mathrm{A}=\left[a_{ij}\right]$and$\mathrm{B}=\left[b_{ij}\right]$be two$3\times 3$real matrices such that$b_{ij}={\left(3\right)}^{\left(i+j-2\right)}{a}_{ij}$, where$i,j=\mathrm{1,2},3$. If the determinant of$\mathrm{B}$ is $81$,   then determinant of$\mathrm{A}$i  s
