(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

2. Relevant equations

my question is more on the second part. I understand that I have to use the indirect proof using contrapositive.

3. 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
