Answer:
After solving the power:

Rectangular form:

Step-by-step explanation:
Given the complex number:

To find:
The indicated power by using De Moivre's theorem.
The complex number in rectangular form.
Rectangular form of a complex number is given as
where a and b are real numbers.
Solution:
First of all, let us have a look at the De Moivre's theorem:

First of all, let us solve:
Let us apply the De Moivre's Theorem:
Here, n = 3
Now, the given complex number becomes:

Let us put the values of
and 

So, the rectangular form of the given complex number is:

The answer for this would be 1.5
