I know this might be a stupid one, but could anyone explain the whole process for me,
X^2= 7 (mod 3^3)

I know this might be a stupid one, but could anyone explain the whole process for me,
X^2= 7 (mod 3^3)
(adding the modulus to 7: 7 + 6(27) = 169)
Why 169? 169 is a perfect square ;)
Does that help now?
