    Simplification

    Simplifying

    2x^1/2 = 6y^2
    2x = (6y^6)^2
    2x = 36y^12

    My math teacher simplified it to x = 18y^12

    Can you clarify?

    Re: Simplification

    Edit: Hang on a second, I've noticed something.

    Is the expression 2x^{\frac{1}{2}} or (2x)^{\frac{1}{2}}?

    Re: Simplification

    Thanks for clarifying, by the way how do I start writing equations the way you do? What are the shortcuts for the neatly displayed formulae?

    Sorry about that, I had to edit my post. See this thread if you're interested in learning to write in LaTex.

    You can use LaTeX tags

    [tex]\sqrt{2x}=6y^2 [/tex] gives  \sqrt{2x}=6y^2
