Homework Statement
1st part , using induction to prvoe that if both x and y are positive then x<y implies x^n<y^n
2nd part, prove the converse, that if both x and y are postive then x^n<y^n implies x<y
Homework Equations
my question is more on the second part. I understand that I have to use the indirect proof using contrapositive.
The Attempt at a Solution
I started with this
If x and y are not positive then it does not imply the following x^n<y^n implies x<y
