    like underoot 2 = p/q

    sqauring both side gives us

    2=p^2/q^2

    2q^2=p^2

    whats meant by this sentence.........
    "a prime no. can be a factor of a square only if it occurs at least twice
    in the square"


    Time doesn't change us, it just unfolds us.

    I think you meant:

    2^2=p^2/q^2

    4q^2=p^2
