If `[(2,-1),(1,0),(-3,4)] A=[(-1,-8,-10),(1,-2,-5),(9,22,15)]`, then sum of all the elements of matrix a is

Find the matrix A such that [(2,-1),(1,0),(-3,4)]A=[(-1,-8,10),(1,2,-5),(9,22,15)] .

Express [(3,2,-4),(4,2,-3),(0,5,1)] as sum of symmetric and skew symmetric matrix.

If A({:(1,3,4),(3,-1,5),(-2,4,-3):})=({:(3,-1,5),(1,3,4),(+4,-8,6):}) , then A=

If A=[(2, 1, 3, 4), (5, 9, -4, sqrt(7)), (3, (5)/(2), 8, 9), (7, 0, 1, 4)] then find the element of a_(43)=___ .

If X= [(2,3,0),(1,-1,5)] ,Y= [(-1,-2,3),(-1,0,2)] ,Z= [(0,4,-1),(5,6,-5)] find 3X+4Y-Z

The matrix [(5,10,3),(-2,-4,6),(-1,-2,x)] is a singular matrix if the value of x is

If A = {:[( 1,1,-2),(2,1,-3),(5,4,-9)]:},find |A|

If A=[[2,-2,-4],[-1,3,4],[1,-2,-3]] then A is 1) an idempotent matrix 2) nilpotent matrix 3) involutary 4) orthogonal matrix
