The complex number is $\"\"$ .

First convert the complex number into trigonometric form.

The trigonometric form is $\"\"$ .

Let, $\"\"$ .

Compare the complex number with a + ib.

a = 3 and b = $\"\"$ 2.

$\"\"$

a = 3 > 0 so, the angle is :

The trigonometric form of $\"\"$ . $\"\"$

$\"\"$

$\"\"$ .

The result is $\"\"$ .
