To solve the expression \(5\log(4) \cdot 4\log(125)\), we can proceed as follows:

### Step 1: Use the logarithm power rule
The power rule of logarithms states that \(a\log(b) = \log(b^a)\). Applying this rule:

\[
5\log(4) = \log(4^5)
\]
\[
4\log(125) = \log(125^4)
\]

### Step 2: Calculate the powers
Next, calculate the values:

\[
4^5 = 1024
\]
\[
125^4 = (5^3)^4 = 5^{12} = 244140625
\]

So, the expression becomes:

\[
\log(1024) \cdot \log(244140625)
\]

### Step 3: Multiply the logarithms
Now, the expression \( \log(1024) \cdot \log(244140625) \) is the final simplified form. If you need to approximate or find a decimal value, you would typically use a calculator or logarithm tables.

However, since the expression was not explicitly requesting a numerical answer, we can leave it as:

\[
\log(1024) \cdot \log(244140625)
\]

This is the simplified form.
