Need help with math


Recommended Posts

i need to prove that u can add 2 irrational numbers and get a rational number, i dont want to complete solution, just something to get me started because i have no clue and the book is not helping me

so a + b = p / q where a and b are irrational and p and q are integers

You could take any irrational number like pie or something and add the negative of it.

e.g. Pie + (-Pie) = 0

Probably not the way you're meant to do it but it works.

thats the only i figured but i dont think thats the way he wants it......if i cant find anything better thats what i'll put....

anyone know a better way?

a direct proof might not work.

Try an indirect proof. Such as proof by contractidiction.

Since it only asks for a single case (implied by the preposition) , a simple example will suffice.

That is entirely correct however, a rational number must be written p/q where q!= 0. Choose p=0, q=1.

Just because its obvious doesn't retract from the fact that it is correct.
