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:
Answer:
3. 8 and 9
4. root 50 and root 144 for they are able to be multiplied to get a whole number/integer
5. 36 feet for the area is calculated be side x side all sides are equal so a number that has a whole root is the number so 36
6. 6 as would be one of the sides of the square rug
Hope this helps. Pls give 5 star, thanks, and brainliest.
It is an obtuse triangle because all of the sides are diffrent amount
9 x 6 = 54 is this right I'll do distributive property next time
Answer:
(-1, 3)
Step-by-step explanation:
x - 5y = -16 [Equation 1]
-x + 3y = 10 [Equation 2]
<u>Adding both equations</u>
- x - x - 5y + 3y = -16 + 10
- -2y = -6
- y = 3
- x - 5(3) = -16
- x - 15 = -16
- x = -1
<u>Solution</u> : (-1, 3)
