The Complex nth Roots Theorem with any nonzero complex number has exactly n ∈ N distinct nth roots.
<h3>
What is a non-zero complex number?</h3>
This is the quantity which does not equal zero is said to be nonzero. A real nonzero number must be either positive or negative, and a complex nonzero number can have either real or imaginary part nonzero.
The roots lie on a circle of radius centered at the origin and spaced out evenly by angles of 2π/n.

The distance of the object from the mirror is 3cm.
To calculate the distance of the object from the mirror, we make use of the mirror formula
<h3>Mirror formula</h3>
- 1/f = (1/u)+(1/v)............ Equation 1
Where:
- f = Focal length of the mirror
- v = image distance
- u = object distance.
Using the real is positive convention,
Given:
Substitute these values into equation 1 and solve for u
- 1/5 = (-1/10)+(1/u)
- 1/5+(1/10) = 1/u
- 1/u = (2+1)/10
- 1/u = 3/10
- u = 10/3
- u = 3.33
- u = 3 cm
Hence, The distance of the object from the mirror is 3cm.

Answer:
Neil Armstrong was the first person to step on the moon on July 20, 1969. Buzz Aldrin and Neil walked around for about three hours. So, both Aldrin and Armstrong were the first, technically speaking.
If this is about proper grammer usage, then option D would be correct.
