Solve for x: /_\=|[2x,3,1],[4,6,x],[3x,1,1]| = 0

Verify that (AB)' = B 'A ' in A=[[1,2,1],[3,2,1]] and B=[[3,1],[1,1],[2,1]]

A = the [[1,1,10,2,31,3,2]]

if A=[[1,2,1],[3,2,3],[2,1,2]] , then a_11 A_11+a_21A_21+a_31A_31 =

If [[1,2],[3,4]] [[3,1],[2,5]]=[[7,11],[k,23]], then write the value of k.

If [[1,2],[3,4]] [[3,1],[2,5]]=[[7,11],[k,23]], then write the value of k.

A= {1, 2, 3, 4, 5, 6}, B= {1, 2, 3, 7, 8, 10}, C= {1, 2, 5, 9, 10}, U= {1, 2,3, 4, 5, 6, 7, 8, 9, 10, 11} Show these sets in Venn diagram.

25/19 + 6/19 = 31/38
