Gdzie robię błąd?

 \sqrt[3]{375}* \sqrt[3]{9}+(3^-^1 - \sqrt[4]{ \frac{16}{81} })^-^2= \sqrt[3]{\frac{3}{8}*9}+(3^-^1 - \sqrt[4]{ \frac{16}{81} })^-^2 =\sqrt[3]{\frac{27}{8}} +(3^-^1 - \sqrt[4]{ \frac{16}{81} })^-^2= \frac{2}{3} + (\frac{1}{3}- \frac{2}{3} )^-^2= \frac{2}{3}(- \frac{1}{3} )^-^2= \frac{2}{3}* (-9 )= -\frac{18}{3}= =-6
