1.Let z0z_0z0 be a root of the quadratic equation x2+x+1=0x^2 + x + 1 = 0x2+x+1=0. If z=3+6iz081−3iz093z = 3 + 6iz_0^{81} - 3iz_0^{93}z=3+6iz081−3iz093, then arg(z)\arg(z)arg(z) is equal to:a.000b.π4\dfrac{\pi}{4}4πc.π6\dfrac{\pi}{6}6πd.π3\dfrac{\pi}{3}3πLogin to continueOnly logged in users canattempt or see the solution.
