The problem consists of three mathematical expressions that involve roots and powers. Let's solve each one step by step.

1. \( \sqrt[3]{0.064 \cdot 343} \)

We can split the multiplication:

\[
0.064 = \left(\frac{4}{10}\right)^3 = \left(0.4\right)^3
\]
\[
343 = 7^3
\]

Now we can simplify the expression inside the cube root:

\[
0.064 \cdot 343 = \left(0.4\right)^3 \cdot 7^3 = (0.4 \cdot 7)^3 = 2.8^3
\]

Thus, the cube root simplifies to:

\[
\sqrt[3]{2.8^3} = 2.8
\]

So, the result of the first expression is \( 2.8 \).

2. \( \sqrt[5]{\frac{7^5}{2^{10}}} \)

We can simplify the expression inside the fifth root:

\[
\sqrt[5]{\frac{7^5}{2^{10}}} = \frac{\sqrt[5]{7^5}}{\sqrt[5]{2^{10}}}
\]

The fifth root of \(7^5\) simplifies to \(7\), and the fifth root of \(2^{10}\) simplifies to:

\[
\sqrt[5]{2^{10}} = 2^{\frac{10}{5}} = 2^2 = 4
\]

Thus, the expression becomes:

\[
\frac{7}{4}
\]

So, the result of the second expression is \( \frac{7}{4} \).

---

3. \( \sqrt[8]{\frac{2^{24} \cdot 3^{16}}{5^{16}}} \)

We can simplify the expression inside the eighth root:

\[
\frac{2^{24} \cdot 3^{16}}{5^{16}} = 2^{24} \cdot \left(\frac{3}{5}\right)^{16}
\]

Now, taking the eighth root of the powers:

\[
\sqrt[8]{2^{24}} = 2^{\frac{24}{8}} = 2^3 = 8
\]

\[
\sqrt[8]{\left(\frac{3}{5}\right)^{16}} = \left(\frac{3}{5}\right)^2 = \frac{9}{25}
\]

So, the expression becomes:

\[
8 \cdot \frac{9}{25} = \frac{72}{25}
\]

Thus, the result of the third expression is \( \frac{72}{25} \).
