I do not know that I could simplify it further.....unless it is a sqrt rather than a cube root....

Welll...... if THAT is simplified, here is an easier way

mutiply by x/x

cube rt(4x/9x^3) = cub rt 4x/9 / x Multiply by 3/3

= cub rt (12x/27) / x

= 1/3x cub rt 12x

= \(\sqrt[3]{12x}\) / 3x Hmmmmmm....my answer is different than Chris'....will check
