The modulus increased by 216 and the argument increased by π/2. Option A is correct
The number that constitutes of real and imaginary numbers are called complex numbers.
[tex]z = 3\sqrt{3} + 3i\\z^4 = (3\sqrt{3} + 3i)^4\\z^4 = 648(-1+\sqrt{3}i )[/tex]
Modulus and argument of [tex]z^4[/tex] is given by.
[tex]|z^4| = 648\sqrt{1+3} \\|z^4| = 648\sqrt{4} \\|z^4| = 648*2\\|z^4| = 1296[/tex]
argument
[tex]\theta=tan^{-1}(\sqrt{3} /-1)\\\theta=tan^{-1}(-\sqrt{3} )\\\theta= -\pi /3[/tex]
similarly, the Modulus and argument of z is given by.
Modulus
|z| = 6
argument
[tex]\theta=\pi /6[/tex]
Now comparing Modulos and argument of [tex]z^4[/tex] and z
[tex]z^4[/tex]/z = 1296/6 = 216
[tex]\theta=\pi /6+\pi /3\\\theta=\pi /2[/tex]
Thus, The modulus increased by 216 and the argument increased by π/2. Option A is correct.
