Olá!

$\big[4,44:(-2,22):(-1,6) \big]^3 + \sqrt{1,69} \\ \\ = \big[ (-2): \big(-\frac{16}{10} \big) \big]^3 + \sqrt{ \frac{169}{100} } \\ \\ = \big[(-2): \big(- \frac{8}{5} \big) \big]^3 + \frac{13}{10} \\ \\ = \big[ (-2) \cdot \big(- \frac{5}{8} \big)^3 \big] + \frac{13}{10} \\ \\ = \Big( \frac{10}{8} \Big)^3 + \frac{13}{10} \\ \\ = \Big(\frac{5}{4} \Big)^3 + \frac{13}{10} \\ \\ = \frac{125}{64} + \frac{13}{10} \\ \: \: \: \: \: (5) \: \: \: \: \: \: (32) \\ \\ = \frac{625 + 416}{320} \\ \\ = \frac{1041}{320}$

Bons estudos!
