Question 1208935
<font color=black size=3>
Answer: <font color=red size=4>False</font>


Reason: 
We just need one counter-example to disprove the claim. Through a bit of trial and error we can generate this {{{sqrt(20)*sqrt(5) = sqrt(20*5) = sqrt(100) = 10}}}


The {{{sqrt(20)}}} and {{{sqrt(5)}}} are each irrational since they individually cannot be expressed as a fraction of two integers. 
But the result 10 = 10/1 is rational since it can be written as a ratio of integers 10 over 1.


This disproves the template <font color=blue>irrational*irrational = irrational</font> as there are some exceptions. 


Note that <font color=blue>irrational*irrational = rational</font> is false as well (try {{{a = sqrt(2)}}} and {{{b = sqrt(3)}}} to see what happens).
