hola,,, question... can I use the rational root test to proof that the cubic root of 2 and square root 3 are irrationals?
sure if you consider the polynomial \[x^3-2\] the rational roots can only be \[\pm 1,\pm2\] and by inspection neither of those work.
cool.. yea i did that... thanks satellite
i guess if you want a real proof you have to know that the root exists, but that is clear because this is a continuous function that takes on both positive and negative values
they are really asking me prove in detail
what u mean the root exist?
