" 28.If "3^(49)(x+iy)=((3)/(2)+(sqrt(3))/(2)i)^(100)" and "x=ky" then "k" is "

If 3^(49)(x+iy)=((3)/(2)+(sqrt(3))/(2)i)^(100) and x=ky then k is: a.-1/3 b.sqrt(3)c.-sqrt(3)d-(1)/(sqrt(3))

If 3^(49)(x+i y)=(3/2+(sqrt(3))/2i)^(100) and x=k y then k is: a. -1//3 b. sqrt(3) c. -sqrt(3) d. -1/(sqrt(3))

(2/(i+sqrt(3)))^(100)+(2/(i-sqrt(3)))^(100)=

x+iy=(1-i sqrt(3))^(100), then (x,y)=

((x+iy)/(2+3i)+(2+i)/(2-3i)=(9)/(13)(1+i)

If ((3)/(2)+ (sqrt(3))/(2))^(50)=3^(25)(x+iy) where x and y are real, then the ordered pair (x,y) is

If ((3)/(2)+i(sqrt(3))/(2))^(50)=3^(25)(x+iy) ,where x and y are real , then the ordered pair (x,y) is -

(x+iy)(2-3i)=4+i
