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:

Step-by-step explanation:
I took the test
The range of values of x as shown in the diagram is -9 < x < 15
<h3>Inequality expressions</h3>
Inequality are expressions not separated by an equal sign. The required inequality expression is given as:
|9x - 27| < 108
For the positive inequality
9x - 27 < 108
9x < 108 +27
9x < 135
x < 15
For the negative inequality
-9x + 27 < 108
-9x < 108 - 27
-9x < 91
x > -9
-9 < x
Hence the range of values of x as shown in the diagram is -9 < x < 15

Answer with step-by-step explanation:
If the ratio for the ingredients is 1:2:3, then the total would be 6. If so, we have to divide 2.1 by 6, which is 0.35. Now, you need to multiply 0.35 to the according ingredient amounts.
Cement: 1 x 0.35 = 0.35
Sand: 2 x 0.35 = 0.70
Quicklime: 3 x 0.35 = 1.05
If you add it up, you will get 2.1, which is the volume.
