Answer:

#2#

Explanation:

A complex number is written in the form #a+bi#. Examples include #3+2i#, #-1-1/2i#, and #66-8i#.

The complex conjugates of these complex numbers are written in the form #a-bi#: their imaginary parts have their signs flipped. They would be: #3-2i,-1+1/2i#, and #66+8i#.

However, you're trying to find the complex conjugate of just #2#. While this may not look like a complex number in the form #a+bi#, it actually is! Think of it this way: #2+0i#

So, the complex conjugate of #2+0i# would be #2-0i#, which is still equal to #2#.

This question is more theoretical than practical, but it's still interesting to think about!
