Question 1136748

What is the simplest form of the radical expression?
The square roots are actually cubic roots, (couldn't figure out how to formulate it)

{{{3sqrt(2a)-6sqrt(2a)}}}
<pre>{{{highlight_green(system(matrix(1,3, 3highlight(x) - 6highlight(x), "=", - 3highlight(x)), so, matrix(1,3, 3 * highlight(root(3, 2a)) - 6 * highlight(root(3, 2a)), "=", - 3 * highlight(root(3, 2a)))))}}}
