I'm wondering how to answer this.

The conjugate of 2-Square root 3 is?

2 + √3

if you have a+b then the conjugate is a-b
if you have a-b then the conjugate is a+b

You are creating the pattern for the difference of squares.

Thank you so much that does make scense. I just posted one more kinda like it if you don't mind explaining?

To find the conjugate of a number of the form a - b√c, you simply change the sign of the term containing the square root (√c).

In this case, the given number is 2 - √3. To find its conjugate, change the sign of √3, so the conjugate is 2 + √3.

Therefore, the conjugate of 2 - √3 is 2 + √3.

To find the conjugate of a complex number, you need to change the sign of the imaginary part.

The given number is 2 - √3.

To find its conjugate, you need to change the sign of √3.

So, the conjugate of 2 - √3 is 2 + √3.
