Complex Numbers

There seems to be a mistake in typing. You probably type the letter "i" as "1", so it is difficult to tell which numbers are complex numbers.

I will however explain what complex numbers look like, which will help you in determining which numbers are complex numbers, and the rest are real numbers.

Step-by-step explanation:

Complex numbers are numbers that include the square root of a negative number.

It is not possible to have a value for an expression with a square root of a negative number, then the letter j or i were introduced to help represent these kinds numbers.

√-1 = i or j (anyone is fine)

Knowing the square root of -1 is i, we can write the square root of any negative number with ease.

√(-6) = √(-1) × √6, right?

= i × √6

= i√6

And so on.

So, basically, the numbers that include the letter 'i', or √(-1) in them are the complex numbers. The rest are real numbers.

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
