[foggy garden]

Recall that conjugate of a+bi is a-bi where a,b $\in\mathbb{R}$

[foggy garden]

so the answer will be √3-√5?

[foggy garden]

No

Does $$\sqrt{3}+\sqrt{5}$$ \have an imaginary part ?

[lilac oasis]

fosur

[foggy garden]

no

so?

[foggy garden]

So look at my definition

Recall that conjugate of a+bi is a-bi where a,b $\in\mathbb{R}$

[lilac oasis]

fosur

[foggy garden]

If b=0

Actually i am not understand so can you tell me the final answet by an explanation and sorry for that 🥲♥@foggy garden

[foggy garden]

So u don’t understand complex numbers

[foggy garden]

So

Just tell me

So I can adapt my explanation

Recall that conjugate of a+bi is a-bi where a,b $\in\mathbb{R}$\ If we are considering real numbers then $b=0$ \so we have the conjugate of $a+(0)i \is\a-(0)i$ \hence conjugate of real number a is a
