" 5.If "A=[[8,7],[-9,-8]]," then "A^(-1)

If A = [{:(8, -7), (9, -8):}], " then " (A^(2007))^(-1) =___.

If A=1/9[[-8,1,4],[4,4,7],[1,-8,4]], show that A^-1=A'.

If A= (1)/(9)[{:(-8,1,4),(4,4,7),(1,-8,4):}],"prove that"" "A^(-1)=A^(T).

If 15/8-7x=9 , then -7x=9+15/8

If A=(1)/(9)[{:(-8,1,4),(4,4,7),(1,-8,4):}] prove that A^(-1)=A^(T) .

If A=1/9[-8 1 4 4 4 7 1-8 4] , prove that A^(-1)=A^T .

Let X ={1,2,3,4,5,6,7,8,9} A= {2,4,5,7,8}, B= {1,3,5,7}, C={4,6,8,9}, then A nn (BuuC)

If A={5,6,7} and B={7,8,9} then A uu B is equal to a) {5,6,7,8,9} b) {5,6,7} c) {7,8,9} d) None of these

If A=(3,5,7,8) and B=(7,8,9,10), then Find the value of (AcupB)-(AcapB) . The following are the steps involved in solving the above problem. Arrange them in sequential order. (A) AcupB=(3,5,,8,9,10) and A capB=(7,8) (B) Given A=(3,5,7,8) and B=(7,8,9,10) (C) (AcupB)-(AcapB)=(3,5,9,10) (D) (AcupB)-(AcapB)=(3,5,7,8,9,10)-(7,8) .
