If `z=-2+2sqrt(3)i,` then `z^(2n)+2^(2n)*z^n+2^(4n)` is equal to

If n is a positive integer but not a multiple of 3 and z=-1+i sqrt(3), then (z^(2n)+2^(n)z^(n)+2^(2n)) is equal to

If z=-2 + 2 sqrt3i then z^(2n) + z^(n) + 2^(4n) may be equal to

If n (ne 3) is an integer and z = -1 + isqrt3 , then z^(2n) + 2^(n) , z^(n) + 2^(2n) =

If n is an integer and z=-1+isqrt3," then "z^(2n)+2^(n).z^(n)+2^(2n)

If n in Z , then (2^(n))/(1+i)^(2n)+(1+i)^(2n)/(2^(n)) is equal to

If z + (1)/(z) = 2 cos theta, z in "C then z"^(2n) - 2z^(n) cos (n theta) is equal to

|z|=1&z^(2n)+1!=0 then (z^(n))/(z^(2n)+1)-(z^(n))/(z^(2n)+1) is equal to

If z_(r)=cos((ralpha)/(n^(2)))+isin((ralpha)/(n^(2))),"where"r=1,2,3,...,nandi=sqrt(-1),"then"lim_(n to oo) z_(1)z_(2)z_(3)...z_(n) is equal to

If z_(1), z_(2),……..,z_(n) are complex numbers such that |z_(1)| = |z_(2)| = …….. = |z_(n)| = 1 , then |z_(1) + z_(2) +……..+ z_(n)| is equal to a) |z_(1)z_(2)z_(3)…..z_(n)| b) |z_(1)|+|z_(2)|+…….+|z_(n)| c) |(1)/(z_(1)) + (1)/(z_(2)) + ……….+ (1)/(z_(n))| d)n
