Simplify:

$\displaystyle {\left(\frac{{{x}^{{{1}}}{y}^{{{2}/{5}}}}}{{{x}^{{{2}/{3}}}{y}^{{{8}/{5}}}{x}^{{{1}/{6}}}}}\right)}^{{{2}}}$

Entry Tip: put the numerator and denominator in parenthesis. Also put the exponents in parenthesis. To type $\displaystyle \frac{{a}^{{\frac{{1}}{{2}}}}}{{b}^{{\frac{{2}}{{3}}}}}$ type (a)^(1/2)/(b^(2/3)). Be sure to use the preview button and be sure you like the format before you hit submit!
