hy guys ,help me

prove if x<y andnis odd ,then x^{n}<y^{n}

i have solved this . .but a question in below

2. Relevant equations

3. The attempt at a solution

if 0=or<x<y then x^{n}<y^{n}(i have proved this ) and if x<y<or=0 we can say 0=or<-y<-x it implies -y^{n}<-x^{n}last we can add both side with +x^{n}and +y^{n}we have x^{n}<y^{n}..

is proved is correct ? and what about if x<y<or=0 ( n is even ) how to prove this ?

thanx before ^_^
