how about $2+\sqrt5$ or $3+\sqrt7$ or $4+\sqrt{10}$ ?

anonymous · Answer

Yeah that's good but why is it conjugate ? I'm having trouble with this chapter ugh -__- difficult trying to understand

anonymous · Answer

the conjugate of $a+\sqrt{b}$ is $a-\sqrt{b}$

anonymous · Answer

so for example the conjugates of each one i wrote above, replace the  $+$ by a $-$

anonymous · Answer

Ohh okay i see now.

anonymous · Answer

so it becomes $$2-\sqrt{5}$$ ?
