Find the values of each of th4e following : 3^(-1)+4^(-1) (ii) (3^0+4^(-1))x2^2 (3^(-1)+4^(-1)+5^(-1))^0 (iv) {(1/3)^(-1)-\ (1/4)^(-1)}^(-1)

Find the value of. (i) (3^@+4^(-1)) xx 2^2 (ii) (2^(-1)xx 4^(-1))-: 2^(-1) (iii) (1/2)^-2 + (1/3)^-2 + (1/4)^-2 (iv) (3^-1 + 4^-1+ 5^(-1))^0 (v) {((-2)/3)^-2}^2

i^4 (1) 0 (2) -1 (3) 1 (4) 2

((0.3)^(1/3)(1/27)^(1/4)(9)^(1/6)(0.81)^(2/3))/((0.9)^(2/3)(3)^(-1/2)(243)^(-1/4))=

If A=[(1,3),(2,4)] and (AB)^(-1)=[((-1)/(2),(1)/(2)),((1)/(4),0)] , then B^(-1). A^(-1)=

Simplify ((3)/(2))^(0)+((1)/(2))^(0)+((1)/(3))^(0)+((1)/(4))^(0)

Let P=[(1,2,0),(-1,3,1),(4,0,-2)]. Q=[(3,-2,1),(-1,4,-1),(0,-4,1)].R=[(3,-2,1),(-1,4,-1),(1,-4,1)] A student throws a die, He chooses the matrix P if he gets 1.if he sets 2 or 4 R if he gets 5 or 6. For the selected matrix (say A) he mart solving the equation |A|x^2+|adj A|x+|adj(adjA)|=0. If the equation is quadratic then the probability that it has real roots is
