Let's go through each problem one by one and solve them.

### Problem 22:
\[
8^6 \cdot 8^5 \cdot 8^2
\]
Since the bases are the same, we can use the property of exponents: \( a^m \cdot a^n = a^{m+n} \). Thus:
\[
8^{6 + 5 + 2} = 8^{13}
\]

### Problem 23:
\[
(16 \cdot 40)^{\frac{3}{8}}
\]
First, calculate \( 16 \cdot 40 = 640 \), so the expression becomes:
\[
640^{\frac{3}{8}}
\]
Now, express 640 as a power of 2: \( 640 = 2^7 \cdot 5 \). Approximating further without exact simplification leads to a more involved calculation, but for now, we can express it as \( (640)^{3/8} \).

### Problem 24:
\[
(3^4)^{\frac{1}{3}}
\]
Using the power of a power rule \( (a^m)^n = a^{m \cdot n} \):
\[
3^{4 \cdot \frac{1}{3}} = 3^{\frac{4}{3}}
\]

### Problem 25:
\[
\frac{32^{19/20}}{32^{3/4}}
\]
Use the quotient rule of exponents \( \frac{a^m}{a^n} = a^{m-n} \):
\[
32^{19/20 - 3/4} = 32^{\frac{19}{20} - \frac{15}{20}} = 32^{\frac{4}{20}} = 32^{\frac{1}{5}}
\]

### Problem 26:
\[
(49 \cdot 9)^{-\frac{1}{2}}
\]
First, calculate \( 49 \cdot 9 = 441 \). So the expression becomes:
\[
441^{-\frac{1}{2}} = \frac{1}{\sqrt{441}} = \frac{1}{21}
\]

### Problem 27:
\[
\left(\frac{625}{16}\right)^{\frac{3}{4}}
\]
We can break this into two parts:
\[
625^{\frac{3}{4}} \quad \text{and} \quad 16^{\frac{3}{4}}
\]
We know \( 625 = 5^4 \), so:
\[
625^{\frac{3}{4}} = 5^3 = 125
\]
And \( 16 = 2^4 \), so:
\[
16^{\frac{3}{4}} = 2^3 = 8
\]
Thus, the final expression is:
\[
\frac{125}{8}
\]
