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?

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

Is the expression $\displaystyle 2x^{\frac{1}{2}}$ or $\displaystyle (2x)^{\frac{1}{2}}$? - Sep 12th 2011, 12:09 PMjon80Re: 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 $\displaystyle \sqrt{2x}=6y^2$
