If `z` is a unimodular complex number then its multiplicative inverse is (i) `barz` (ii) `z` (iii)`-z` (iv)`-barz`

If z is a nonzero complex number then (bar(z^-1))=(barz)^-1 .

If z= 4+ 7i be a complex number, then find (i) Additive inverser of z. (ii) Multiplicative inverse of z.

If z= 4+ 7i be a complex number, then find (i) Additive inverser of z. (ii) Multiplicative inverse of z.

Find the complex number z if z^2+barz =0

Z is a complex number and Z. barZ=0 , it is true only when

If z is a non zero complex, number then |(|barz |^2)/(z barz )| is equal to (a). |(barz )/z| (b). |z| (c). |barz| (d). none of these
