Answer 1

$\displaystyle\bf\\\Big(-a^{2} b\Big)^{4} \cdot\Big(-2ab^{3} \Big)^{3}\cdot\Big(\frac{2}{3} ab^{2} \Big)^{3} \cdot 6 \frac{3}{4} a^{5} b=\\\\\\=a^{8} b^{4} \cdot\Big(-8a^{3} b^{9} \Big)\cdot\frac{8}{27} a^{3} b^{6} \cdot \frac{27}{4} a^{5} b=\\\\\\=-\frac{8\cdot 8\cdot27}{27\cdot 4} \cdot a^{8+3+3+5} \cdot b^{4+9+6+1} =-16a^{19} b^{20}$
