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

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

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)] , 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 A = { 2 , 5, 8 , 7 } , B = { 6 , 7, 8 , 9 } ,then A ∩ B = A) { 5 , 8 , 7 } B) { 2 , 5, 7 } C ) { 7, 8 }

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 .

Let A = {7, 8, 9, 10} and R = {(8, 8), (9, 9), (10, 10), (7, 8)} be a relation on A, then R is

{:(10,85,8),(7,54,7),(8,?,9):}

If A=[(0, 4, 9), (8, 3, 7)], B=[(7, 3, 8), (1, 4, 9)] find the value of 3A-9B
