JEE MainMathematicsMatrices and DeterminantsNumerical+4 / −1
Let AAA be a square matrix of order 3 such that det⁡(A)=−2\operatorname{det}(A)=-2det(A)=−2 and det⁡(3adj⁡(−6adj⁡(3A)))=2m+n⋅3mn,m>n\operatorname{det}(3 \operatorname{adj}(-6 \operatorname{adj}(3 A)))=2^{m+n} \cdot 3^{m n}, m>ndet(3adj(−6adj(3A)))=2m+n⋅3mn,m>n. Then 4m+2n4 m+2 n4m+2n is equal to ‾\underline{\hspace{2cm}}​.
