Question 1139810
<pre>
With that little 3 there it's not a square root but a cube root.

{{{root(3,27/512)}}} <-- "cube root of 27 over 512." 

Since 27 = 3•3•3 = 3<sup>3</sup> and 512 = 8•8•8 = 8<sup>3</sup>, the above
becomes: 

{{{root(3,(3/8)^3)}}}

and the cube root and the cube cancel each other out and just leave this:

Answer:  {{{3/8}}}
