Given z^3 = 3 + square root 3i which letter represents z

Marianna [84]

The expression that represents the value of z is $\sqrt[3]{3 + i\sqrt 3 }$

<h3>What are complex numbers?</h3>

Complex numbers are numbers that have real and imaginary parts

A complex number (n) is represented as:

$n = a + bi$

From the above expression, we have:

a represents the real part
bi represents the imaginary part

Given that:

$z^3 = 3 + \sqrt 3 i$

Rewrite the above expression as:

$z^3 = 3 + i\sqrt 3$

Take the cube roots of both sides

$z = \sqrt[3]{3 + i\sqrt 3 }$

The letters are not given.

Hence, the expression that represents the value of z is $\sqrt[3]{3 + i\sqrt 3 }$
