Matrix A=[{:(0,2y,z),(x,y,-z),(x,-y,z):}] if A A^(T)=I then , (x,y,z)=(...,...,...)(x,y,zgt0)

x_1,x_2, x_3,………., x_n are n observations . sum_(i=1)^(n) (x_i - 2) = 100 " and " sum_(i=1)^(n) (x_i - 5) = 20 then mean barx = …….

If i= (sqrt-1) , prove that following (x+1+i) (x+ 1-i) (x-1-i) (x-1+ i)= x^(4) + 4
