Question

RESOLVER EM FORMA DE FRAÇÃO [- 0,1+ (-2,1 +0,5) – (-0,1)³ ]² =

Answer 1

$(- \frac{1}{10} + ( - \frac{21}{10} + \frac{5}{10} ) - (- { \frac{1}{10} })^{3} )^{2} = \\ \\ ( \frac{ - 1 - 21 + 5}{10} - ( -\frac{1}{1000} ))^{2} = \\ \\ ( \frac{ - 17}{10 }+ \frac{1}{1000} )^{2} = ( \frac{ - 1700 + 1}{1000} )^{2} = \\ \\ ( - \frac{1699}{1000} )^{2} = \frac{( - 1699)^{2}}{1000000} = \\ \\ \frac{2886601}{1000000} = 2,8866$
