Hello all, i could use some help with a problem i cant quite figure out how to prove. I'll keep trying, but any help in the meantime would be greatly appreciated.

"If x^4 is irrational, then x is irrational" ...Prove true for all Real #'s.

Is the converse true for all Real #'s x ? (If x is irrational, then x^4 is irrational)

Thank you,

Kyle
