`|(2,3),(4,5)|`

If A=[{:(2,3),(4,5):}] , show that (A-A') is skew-symmetric.

If A={1, 2, 3, 4, 5} and R:ArarrA is {(1,2), (2,3), (4,5), (3,3)} then write R^-1:ArarrA .

Express the following as the sum of symmetric and skew - symmetric matrices : [(3,2,3),(4,5,3),(2,4,5)]

If A={:[(1,2,3),(4,5,6)]:} , then A^(T) = ________ .

If A=[{:(2,3),(-4,5):}]andB=[{:(1,-2),(3,4):}]

15. For matrix A=[(2,3),(-4,5)] , (adjA)^T is equal to (A) [(5,-3),(4,2)] (B) [(5,4),(-3,2)] (C) [(5,3),(4,-2)] (D) [(5,-3),(-4,2)]

15. For matrix A=[(2,3),(-4,5)] , (adjA)^T is equal to (A) [(5,-3),(4,2)] (B) [(5,4),(-3,2)] (C) [(5,3),(4,-2)] (D) [(5,-3),(-4,2)]

Find the matrix A such that A.[{:(2,3),(4,5):}]=[{:(0,-4),(10," "3):}].
