Step 1:

De Moivres Theorem :

If $\"image\"$ is a complex number, then

$\"image\"$ where $\"image\"$ is a positive integer.

Step 2:

The complex number is $\"\"$ .

The complex number $\"\"$ .

$\"\"$

Write the complex number in polar form.

$\"\"$

The argument is $\"\"$ .

$\"\"$

Polar form of $\"\"$ is $\"\"$ .

De Moivre\\'s theorem: $\"\"$

Then, raise the complex number to given power.

$\"\"$

Solution:

$\"\"$
