Question

determine o valor da expressão
$(1 + \frac{1}{3} ){2} - ( - \frac{1}{3} )3 +( \frac{3}{2} )- 2$
​

Answer 1

$(1+\frac{1}{3})2-(-\frac{1}{3})3+(\frac{3}{2})-2=$

$(2+\frac{2}{3})-(-1)+\frac{3}{2}-2=$

$\frac{12}{6}+\frac{4}{6}+\frac{6}{6}+\frac{9}{6}-\frac{12}{6}=$

$\frac{12+4+6+9-12}{6}=$

$\frac{19}{6}$
