r=(3+1)^1/2=4^1/2=2                                                                                                     √3+i=2(√3/2+i/2) =2(cosπ/6+i sinπ/6)                                                                         (√3+i)^3 =2^3(cos 3π/6+i sin 3π/6) =8(cosπ/3+i sin π/3) =8(1/2+i√3/2) =4+4√3
