Let the determinant of a `3 xx 3` matrix `A` be `2` then `B` is a matrix defined by `B=5A^2` Then `det` of `B` is (A) 20 (B) 10 (C) 40 (D) 500

A is a 3xx4 matrix .A matrix B is such that A'B and BA' are defined . Then the order of B is ……..

If A is a 3xx3 matrix and B is a matrix such that A^TB and BA^(T) are both defined, then order of B is

If A is a 3xx3 matrix and B is a matrix such that A^TB and BA^(T) are both defined, then order of B is

If each element of a 3xx3 matrix A is multiplied by 3 then the determinant of the newly formed matrix is (A) 3detA (B) 9 detA (C) (detA)^3 (D) 27 det A

If each element of a 3xx3 matrix A is multiplied by 3 then the determinant of the newly formed matrix is (A) 3detA (B) 9 detA (C) (detA)^3 (D) 27 det A

If A is an invertible matrix of order 2, then det (A^(-1)) is equal to (A) det (A) (B) 1/(det(A) (C) 1 (D) 0

If A is matrix of a order 2 xx 3 and B is a matrix of order 3 xx 2 , then AB is a matrix of order:
