The question in the image asks to rewrite each expression as a single power (bilangan berpangkat). I'll solve each part individually:

### a. \( \sqrt{5} \cdot \sqrt{5} \)

We can write square roots as fractional exponents:

\[
\sqrt{5} = 5^{\frac{1}{2}}
\]

Thus:

\[
\sqrt{5} \cdot \sqrt{5} = 5^{\frac{1}{2}} \cdot 5^{\frac{1}{2}} = 5^{\frac{1}{2} + \frac{1}{2}} = 5^1 = 5
\]

### b. \( \sqrt[3]{7} \cdot \sqrt[3]{7} \)

Cube roots can be expressed as fractional exponents:

\[
\sqrt[3]{7} = 7^{\frac{1}{3}}
\]

Thus:

\[
\sqrt[3]{7} \cdot \sqrt[3]{7} = 7^{\frac{1}{3}} \cdot 7^{\frac{1}{3}} = 7^{\frac{1}{3} + \frac{1}{3}} = 7^{\frac{2}{3}}
\]

### c. \( \sqrt[5]{13} \cdot \sqrt[5]{13} \)

Similarly:

\[
\sqrt[5]{13} = 13^{\frac{1}{5}}
\]

Thus:

\[
\sqrt[5]{13} \cdot \sqrt[5]{13} = 13^{\frac{1}{5}} \cdot 13^{\frac{1}{5}} = 13^{\frac{2}{5}}
\]

### d. \( \frac{\sqrt{3}}{\sqrt{3}} \)

Since both numerator and denominator are the same, this simplifies to:

\[
\frac{\sqrt{3}}{\sqrt{3}} = 1
\]

### e. \( \frac{\sqrt[3]{7}}{\sqrt[7]{7}} \)

Here we express the roots as exponents:

\[
\sqrt[3]{7} = 7^{\frac{1}{3}}, \quad \sqrt[7]{7} = 7^{\frac{1}{7}}
\]

Using the quotient rule for exponents:

\[
\frac{7^{\frac{1}{3}}}{7^{\frac{1}{7}}} = 7^{\frac{1}{3} - \frac{1}{7}} = 7^{\frac{7-3}{21}} = 7^{\frac{4}{21}}
\]

### f. \( \frac{\sqrt[5]{7}}{\sqrt[7]{7}} \)

Again, expressing the roots as exponents:

\[
\sqrt[5]{7} = 7^{\frac{1}{5}}, \quad \sqrt[7]{7} = 7^{\frac{1}{7}}
\]

Using the quotient rule:

\[
\frac{7^{\frac{1}{5}}}{7^{\frac{1}{7}}} = 7^{\frac{1}{5} - \frac{1}{7}} = 7^{\frac{7-5}{35}} = 7^{\frac{2}{35}}
\]
