This should be an easy question but I'm having problems with it. Prove that any number that ends in five when squared equals 25. So if n is the number then(adsbygoogle = window.adsbygoogle || []).push({});

(n/5)^2 = (n^2)/25

Although if you expand the left side then this statement is redudant. Can someone help me with this?
