If `A=[(5,3),(5,4)]` , then `A^(2)` is equal to:

If A=[(5,4),(3,2)] then A^(-1) is equal to

If A =[(1,2),(3,4)] then A^(2)-5A equals

2(2/3) // 5 is equal to:

If A={:[(1,2,3),(-2,5,7)]:}and2A-3B={:[(4,5,-9),(1,2,3)]:} then B is equal to

15. For matrix A=[(2,3),(-4,5)] , (adjA)^T is equal to (A) [(5,-3),(4,2)] (B) [(5,4),(-3,2)] (C) [(5,3),(4,-2)] (D) [(5,-3),(-4,2)]

If A=([4,2],[5,6]) then |A'| is equal to

Let A={:[(2,3,5),(1,0,2),(3,4,5)]:}andA+B-4I=0 , then B is equal to

((2)/(3))^(-5) is equal to

If a=2+sqrt(3)+sqrt(5) and b=3+sqrt(3)-sqrt(5) , then a^(2)+b^(2)-4a-6b-3 is equal to
