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

IF [{:(3,5,3),(2,4,2),(lamda,7,6):}] is a singular matrix, then write the value of lamda

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

Express the marix A=|{:(3,2,3),(4,5,3),(2,4,5):}| as the sum of a symmetric matrix and a skew-symmetric matrix.

If A = [(3,-5),(-4,2)] then show that A+A' is a symmetric matrix.

Express the matrix A=|(3, 2 ,3),(4,5 ,3),( 2, 4,5)| as the sum of a symmetric and a skew-symmetric matrix.

{:(3,4,5),(2,3,4),(1,2,3),(14,29,?):}

If A=[(1,-2,3),(-4,2,5)],B=[(2,3),(4,5),(2,1)] then

((5.3)^(2)-(4.7)^(2))/(5.3-4.7) is equal to

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