hey guys so im kinda stuck on surds again
umm how can you tell what is a surd and what isnt a surd?
and how are they irrational or not
thanks.
First of all , irrational numbers are numbers which cannot be expressed in the form $\displaystyle \frac{m}{n}$ , where m and n are integers . Examples of irrational numbers are $\displaystyle \sqrt{2}$ and
$\displaystyle 2\sqrt{3}+\sqrt{5}$ . Thus , irrational numbers such as these are also called surds .
Does that answer your question ?
