    List some squares. What do the last digits have in common?

    If a number's squareroot is 7.5 for example, how would I find that number?

    Could you perhaps explain what you don't get? I don't know how to word it. Here's a mathworld site on squaring if you want to check it out - http://mathworld.wolfram.com/SquareNumber.html.
