true or false the product of two irrational numbers is always an irrational number

OpenStudy (anonymous):

if you add a never ending number to a never ending number what do you get?

OpenStudy (dumbcow):

True

OpenStudy (anonymous):

What's your logic? I mean, the square root of 2 times the square root of 8 is the square root of 16 which is rational...

OpenStudy (dumbcow):

haha oops i feel dumb. thanks

OpenStudy (anonymous):

so is it true or false

OpenStudy (dumbcow):

dont listen to me, read what branlegr said

OpenStudy (anonymous):

false

OpenStudy (anonymous):

explain why you said false

OpenStudy (anonymous):

If you can come up with a counterexample to the statement, then the statement is false. sqrt(2) and sqrt(8) are two irrational numbers. If you multiply them together, you get sqrt(16) = 4. Since 4 is a rational number, you have shown that the product of two irrational numbers is not ALWAYS an irrational number.
