1.	If x `prop ` y then x^(n) `prop`
Answer» `x propy rArr x =ky` ( k =non zero variation constant ) `rArr (x)^(n) =(ky)^(n) ` (taking n-th power ) `rArr x^(n) =k^(n).y^(n). ` `rArrn^(n)=my^(n)` (when m =`k^(n) ne0=`variation constant ) `rArr x^(n)prop y^(n)` (`because` m =non -zero variation constant ). `therefore x^(n) propy^(n) .`
