Explicação passo-a-passo:

(\frac{5}{3} )^{2} - (-\frac{1}{6} )^{2}\\\\(\frac{5}{3} ) . (\frac{5}{3} ) - (-\frac{1}{6} ) . (-\frac{1}{6} )\\\\(\frac{25}{9} ) - (\frac{1}{36} )\\\\\frac{100-1}{36} \\\\\frac{99}{36} : \frac{9}{9} = \frac{11}{4}

(-0,6)³ + (-1,5)²

(-\frac{6}{10})^{3}  + (-\frac{15}{10})^{2} \\\\(-\frac{6}{10}) . (-\frac{6}{10}) . (-\frac{6}{10}) + (-\frac{15}{10}) . (-\frac{15}{10})\\\\(-\frac{216}{1000}) + (\frac{225}{100})\\\\\frac{-216+2250}{1000} \\\\\frac{2034}{1000} = 2,034

(1,1)³ . 2 - (-0,2)³ + 3

(\frac{11}{10})^{3}  .  2 - (-\frac{2}{10})^{3} + 3\\\\(\frac{11}{10}) . (\frac{11}{10}) . (\frac{11}{10}) . 2 - (-\frac{2}{10}).(-\frac{2}{10}).(-\frac{2}{10}) + 3\\\\(\frac{1331}{1000}) . 2 - (-\frac{8}{1000}) +3\\\\(\frac{2662}{1000}) - (-\frac{8}{1000}) + \frac{3}{1} \\\\\frac{2662 + 8 + 3000 }{1000}\\\\\frac{5670}{3000} : \frac{3}{3} = \frac{1890}{1000} = 1,890

(-\frac{3}{2} )^{2} . (-\frac{8}{27} ) - (\frac{1}{2} )^{3} : (-\frac{3}{16} )\\\\(-\frac{3}{2} ) . (-\frac{3}{2} ) . (-\frac{8}{27} ) - (\frac{1}{2} ) . (\frac{1}{2} ) . (\frac{1}{2} ) : (-\frac{3}{16} )\\\\(\frac{9}{4} ) . (-\frac{8}{27} ) - (\frac{1}{8} ) : (-\frac{3}{6} )\\\\(-\frac{72}{108} ) - (\frac{1}{8} ) . (-\frac{6}{3} )\\\\(-\frac{72}{108} ) - (-\frac{6}{24} ) \\\\(-\frac{72}{108} ) + \frac{6}{24}\\\\\frac{-1944 + 36}{4}\\\\ \frac{-1908}{4} = -477
