Answer 1

Решение и ответ:

$\displaystyle \[{\left( {9{a^2}c} \right)^2}={9^2}{\left( {{a^2}} \right)^2}{c^2}=81{a^{2 \cdot 2}}{c^2}=\boxed{81{a^4}{c^2}}$

$\displaystyle {\left({-0.1{c^3}d} \right)^4}={\left( {-0.1} \right)^4} \cdot {\left( {{c^3}} \right)^4} \cdot {d^4}=0.0001{c^{3 \cdot 4}} \cdot {d^4}=\boxed{0.0001{c^{12}} \cdot {d^4}}$

$\[8{x^2} \cdot \left( {\frac{3}{{16}}y} \right) = 8 \cdot \frac{3}{{16}}{x^2}y = \boxed{\frac{3}{2}{x^2}y}\]$

$\displaystyle 2\frac{1}{3}{m^2}{h^2} \cdot 5\frac{1}{7}mh=2\frac{1}{3} \cdot 5\frac{1}{7} \cdot {m^2}{h^2} \cdot mh=\frac{7}{3} \cdot \frac{{36}}{7} \cdot {m^2}m \cdot {h^2}h=12{m^{2+ 1}}{h^{2+1}}=\boxed{12{m^3}{h^3}}$
