The problem you uploaded involves finding the exact value of two expressions:

### (a) \( 4 \left( \log_4 7 + \log_4 4 \right) \)

Using logarithmic rules, we can simplify the expression step by step:
1. Use the property \( \log_b b = 1 \). So, \( \log_4 4 = 1 \).
   
   This simplifies the expression to:
   \[
   4 \left( \log_4 7 + 1 \right)
   \]

2. Now distribute the 4:
   \[
   4 \cdot \log_4 7 + 4 \cdot 1 = 4 \log_4 7 + 4
   \]

3. Using the logarithmic property \( a \log_b x = \log_b (x^a) \), the term \( 4 \log_4 7 \) can be rewritten as:
   \[
   \log_4 (7^4) = \log_4 2401
   \]

Thus, the expression becomes:
\[
\log_4 2401 + 4
\]
This is the simplified form.

### (b) \( e^{6 \ln(2)} \)

To simplify this, we can use the logarithmic identity \( e^{\ln(x)} = x \), which gives:
\[
e^{6 \ln(2)} = 2^6 = 64
\]

So, the exact value of the second expression is:
\[
64
\]
