The image contains two mathematical problems written in Indonesian involving logarithms. Here's the translation and the questions:

**Question 2:**
"Tentukan nilai dari \( ^5\log 15 + ^5\log 5 - ^5\log 3 \)"
Translation: "Determine the value of \( ^5\log 15 + ^5\log 5 - ^5\log 3 \)"

**Question 3:**
"Tentukan nilai dari \( ^7\log 3 \cdot ^5\log 49 \cdot ^9\log 25 \)"
Translation: "Determine the value of \( ^7\log 3 \cdot ^5\log 49 \cdot ^9\log 25 \)"

Let me solve these problems one by one.

### Question 2: \( ^5\log 15 + ^5\log 5 - ^5\log 3 \)

This is a combination of logarithms with the same base, so we can apply the logarithmic rules.

1. Combine the logarithms:
\[
^5\log(15 \cdot 5 / 3)
\]
Simplifying:
\[
^5\log(75 / 3) = ^5\log 25
\]

2. Since \( 25 = 5^2 \), we can use the property of logarithms: \( ^a\log b^n = n \cdot ^a\log b \):
\[
^5\log 25 = 2 \cdot ^5\log 5 = 2
\]

So, the value of the expression is **2**.

### Question 3: \( ^7\log 3 \cdot ^5\log 49 \cdot ^9\log 25 \)

Let's simplify each logarithm term:
1. \( ^7\log 3 \)
2. \( ^5\log 49 \) — Since \( 49 = 7^2 \), this becomes:
   \[
   ^5\log 49 = 2 \cdot ^5\log 7
   \]
3. \( ^9\log 25 \) — Since \( 25 = 5^2 \), this becomes:
   \[
   ^9\log 25 = 2 \cdot ^9\log 5
   \]

The final expression becomes:
\[
^7\log 3 \cdot 2 \cdot ^5\log 7 \cdot 2 \cdot ^9\log 5
\]

This product simplifies each logarithmic value.
