If `X=[[-x, -y], [z, t]]`, then transpose of adjX is

IF X=[[-x,-y],[z,t]] , then transpose of adj X is

If A=[(-x,-y),(z,t)] , then the transpose of adj A is -

Consider the matrix A=[(x, 2y,z),(2y,z,x),(z,x,2y)] and A A^(T)=9I. If Tr(A) gt0 and xyz=(1)/(6) , then the vlaue of x^(3)+8y^(3)+z^(3) is equal to (where, Tr(A), I and A^(T) denote the trace of matrix A i.e. the sum of all the principal diagonal elements, the identity matrix of the same order of matrix A and the transpose of matrix A respectively)

If [(x+y,y-z),(5-t,7+x)]=[(t-x,z-t),(z-y,x+z+t)] , then find the values of x, y, z and t.

If A={x,y,z,t} then which of these is not true: (a) x in A (b) {y,z}sub A (c) t sub A (d) w!in A

If x, y, z, t are odd natural numbers such that x + y + z +t=20 then find the number of values of ordered quadruplet (x, y, z, t).

If x, y, z, t are odd natural numbers such that x + y + z +w=20 then find the number of values of ordered quadruplet (x, y, z, t).

If x, y and z are the roots of the equation 2t^(3)-(tan[x+y+z]pi)t^(2)-11t+2020=0 , then |(x,y,z),(y,z,x),(z,x,y)| is equal to (where, [x] denotes the greatest integral value less than or equal to x)
