Because if you multiply 2 different irrational numbers (like the following)
You will get an irrational answer.
BUT
if you multiply the same square root (which are both irrational, you get a rational number)
You will get an irrational answer.
BUT
if you multiply the same square root (which are both irrational, you get a rational number)
