If `A=(3 5 7 9)` is written as A = P + Q, where P is a symmetric matrix and Q is skew symmetric matrix, then write the matrix P.

If A=([3,57,9]) is written as A=P+Q where P is a symmetric matrix and Q is skew symmetric matrix,then write the matrix P.

If A=[3 5 7 9] is written as A=P+Q , where P is symmetric and Q is skew-symmetric matrix, then write the matrix P .

If A=[3579] is written as A=P+Q where as A=P+Q, where P is symmetric and Q is skew-symmetric matrix,then write the matrix P.

If [(3,5),(7,9)] is written as A + B, where A is the skew-symmetric matrix and B is the symmetric matrix, then write the matrix A.

A is a symmetric matrix or skew symmetric matrix. Then A^(2) is

If A=[(1, 2),( 0, 3)] is written as B+C , where B is a symmetric matrix and C is a skew-symmetric matrix, then find Bdot

If A=[[1,20,3]] is written as B+C, where B is a symmetric matrix and C is a skew- symmetric matrix,then find B.

Let A = [[2,3],[a,0]], a in R be written as P + Q where P is a symmetric matrix and Q is skew symmetric matrix. If det(Q) = 9, then the modulus of the sum of all possible values of determinant of P is equal to :

If A=[(2,3),(1,0)]=P+Q , where P is symmetric and Q is skew-symmetric, then find the matrix P.
