see here on how to write radical signs as powers.
then notice that
Can you take it from here?
Hi, I'm trying to understand how this expression is simplified. (Disclaimer: I don't know how to get this expression into the text here - so have entered it in Grapher, taken a screenshot, and attached it. If anyone could point me to the relevant FAQ on how to enter this kind of expression directly, I'd be much obliged).
The answer given is the second screen shot.
Thanks for your help.
Thanks for both the hint and the tips on writing exponents for the forum. Having said that, your link doesn't show how you entered your equation, which shows up in my browser as an image link with the source showing
So how do you do that?<a href="javascript:;" onclick="do_texpopup('\\sqrt[3] {b^2 \\sqrt {b}} = \\left( b^2 \\cdot b^{\\frac {1}{2}} \\right)^{\\frac {1}{3}}', 'math'); return false;"><img src="http://www.mathhelpforum.com/math-help/latex2/img/d8b692684f32d78cd66af4e9e3154f62-1.gif" alt="\sqrt[3] {b^2 \sqrt {b}} = \left( b^2 \cdot b^{\frac {1}{2}} \right)^{\frac {1}{3}}" title="\sqrt[3] {b^2 \sqrt {b}} = \left( b^2 \cdot b^{\frac {1}{2}} \right)^{\frac {1}{3}}" style="border: 0px; vertical-align: middle;" /></a
My problem was that I was looking at the b^2 part as being the index of b^(1/2), instead of just realizing that it was a simple multiplication of b^2 with b^(1/2).
I'm sorry, i don't know what you are referring to here. are you talking about the pretty-math typing, or the diagram with the flower?
so, are you able to work out the answer now? what is the answer?

yes, I understand. What I'm trying to say is that the way your answers are graphically represented in my browser is better than just typing
b^(5/6)
as an example; your answers look like real equations! Are you typing in all that extra code
\boxed { b^{5/6} }
or is there a simpler way of doing it?
