Us question ka answer mil sakta hai
Simple rule, jis kisi ka perfect square check karna ho, Uska factor kar do, iske baad check kar lo ki sb number double double hai ya nhi, If nhi to perfect square nhi bn skta, Ex - 225. Ab pahle 225 la factor karna hai to, 225 = 3×3×5×5,. Ab yahan dekhna hai ki 3 do baar hai or 5 bhee do baar hai iska matlb 225 perfect square hai, If 3 do baar nhi rahkar 3 baar ya 5 baar ya 1 hi baar rahta to fir 225 perfect square nhi banta. ok
