Answer 2

Объяснение:

$\[\begin{gathered}{10^3}-{5^2}:8+{\left( {\frac{2}{3}} \right)^5}*81=1007\frac{{13}}{{24}} \hfill \\1){5^2}:8=25:8=3,125 \hfill \\2){\left({\frac{2}{3}}\right)^5}*81=\frac{{{2^5}}}{{{3^5}}}*81=\frac{{32}}{{243}}*81= \frac{{32}}{3}\hfill \\3){10^3}-3,125=1000-3,125=996,875\hfill \\4)996,875+\frac{{32}}{3}=1007\frac{{13}}{{24}}\hfill \\\end{gathered} \]$

$\[\begin{gathered}{9^3} - {15^2}:16+{\left( {\frac{3}{4}}\right)^3}:\frac{{27}}{{32}}=715,4375 \hfill \\1){15^2}:16=225:16=\frac{{225}}{{16}} \hfill \\2){\left( {\frac{3}{4}}\right)^3}:\frac{{27}}{{32}}={\left( {\frac{3}{4}}\right)^3}*\frac{{32}}{{27}}=\frac{{{3^3}}}{{{4^3}}}*\frac{{32}}{{{3^3}}}=\frac{{32}}{{64}}=\frac{1}{2}=0,5\hfill \\3){9^3}-\frac{{225}}{{16}}=729-\frac{{225}}{{16}}=714,9375 \hfill \\4)714,9375+0,5=715,4375\hfill \\\end{gathered} \]$
