Answer 2

$3ab^{2} + [ 8ab- [\frac{8}{5} a^{2}b : 4a +\frac{1}{5} ab - (3ab^{2}:10b)]].5b=\\\\ 3ab^{2} +[ 8ab- [\frac{2}{5} a^{2-1} b +\frac{1}{5} ab - (\frac{3}{10}ab^{2-1} ]].5b=\\ \\3ab^{2} + [ 8ab- [\frac{3}{5} a b - \frac{3}{10}ab ]].5b=\\\\\3ab^{2} + [ 8ab- [\frac{6ab-3ab}{10}]].5b=\\\\3ab^{2}+ [ 8ab- \frac{3ab}{10}]].5b=\\\\\3ab^{2} +[ \frac{80ab-3ab}{10}]].5b=\\\\\3ab^{2} + [ \frac{77ab}{10}]] .5b=\\\\3ab^{2}+ \frac{385 ab^{2} }{10} =$

$\\\frac{30ab^{2}+385ab^{2} }{10} =\\\\\frac{415:5ab^{2} }{10:5}=\\\\\frac{83ab^{2} }{2}$

Espero que esteja certo . kk
