Anybody knows if they ' re issuing a refund in India ? <| sep |> Yes , please , that ' d be great . <| sep |> I am assuming you meant the square root of x 7 . I am assuming also you know when and when not to use paranthesises and brackets . You are correct in identifying that 7 itself won ' t be in the rangeI can choose 6 . 5 to be x , and I ' ll still get a positive number in the radical that isn ' t zero , so 6 . 5 is in the range . Now if I choose 7 exactly , I ' ll zero in the denominator so it isn ' t in the range , but every number that ' s close to 7 6 tel 99 for instance will be in the range because the square root of 6 . 9999999997 is like . 000001 , which is allowed in the range . <| sep |> I love it too . I even love engineers . <| sep |> It ' s almost like film is some sort of subjective art form .
