[" If "n" is an integer and "],[(1+i sqrt(3))^(n)+(1-i sqrt(3))^(n)=2^(n+1)cos theta" then "],[theta=]

If n is positive integer and (1+isqrt3)^n+(1-isqrt3)^n=2^(n+1) cos theta , then the value of theta is

If ((1+i sqrt(3))/(1-i sqrt(3)))^(n) is an integer, then n=

If n is a positive integer, then: (sqrt(3)+1)^(2n)-(sqrt(3)-1)^(2n) is:

n is any integer then arg(((sqrt(3)+i)^(4n+1))/((1-sqrt(3)i)^(4n)))=....

((1+i sqrt(3))/(1-i sqrt(3)))^(n) is an integer,then n is

((-1+i sqrt(3))/(2))^(3 n)+((-1-i sqrt(3))/(2))^(3 n)=

Prove that (a)(1+i)^(n)+(1-i)^(n)=2^((n+2)/(2))*cos((n pi)/(4)) where n is a positive integer. (b) (1+i sqrt(3))^(n)+(1-i sqrt(3)^(n)=2^(n+1)cos((n pi)/(3)), where n is a positive integer

If n is a possible integer, then (sqrt3+1)^(2n)-(sqrt3-1)^(2n) is
