" 15."(0.bar(1))^(2){1-9(0.1bar(6))^(2)}

(0.bar1)^(2)[1-9(0.bar(16))^(2)]=?

For two unimodular complex numbers Z_(1) and Z_(2), [(bar(z_(1)),-z_(2)),(bar(z_(2)),z_(1))]^(-1)[(z_(1),z_(2)),(-bar(z_(2)),bar(z_(1)))]^(-1) is equal to a) [(z_(1),z_(2)),(bar(z)_(1),bar(z)_(2))] b) [(1,0),(0,1)] c) [(1//2,0),(0,1//2)] d)None of these

{:("Quantity A","Quantity B"),((0.bar7)(0.8)(35),(1.8)(15)(0.bar7)):}

1.bar(5)+2.bar(6)+3.bar(7)=

If z_(1),z_(2),z_(3) are three complex numbers such that 5z_(1)-13z_(2)+8z_(3)=0, then prove that [[z_(1),(bar(z))_(1),1z_(2),(bar(z))_(2),1z_(3),(bar(z))_(3),1]]=0

Evaluate 2.bar(6)+0.bar(9)
