    Squaring Square Roots

    Hi All,
    Quick one, what are the rules governing [tex](6\sqrt{12})^2)[\MATH]. ( Sorry Latex won't compile for me: 6 times the squares root of 2 squared) The answer is 72 but not sure how I get there.

    Thanks,

    That simple? Thanks. I wonder why the latex is compiling for me, must be a firewall.

    Appreciate it once again Plato.
