Solve the equation by using properties of the logarithm function. Enter the value of x rounded to four decimal places.
4×log(7^x)=52

To solve the equation \( 4 \times \log(7^x) = 52 \) using the properties of logarithms, follow these steps:

### Step 1: Apply the logarithm power rule
The logarithm power rule states that \( \log(a^b) = b \times \log(a) \). So, we can rewrite the equation as:
\[
4 \times x \times \log(7) = 52
\]

### Step 2: Isolate the logarithmic term
Next, divide both sides of the equation by 4 to isolate the \( x \times \log(7) \) term:
\[
x \times \log(7) = \frac{52}{4}
\]
\[
x \times \log(7) = 13
\]

### Step 3: Solve for \( x \)
Now, divide both sides of the equation by \( \log(7) \) to solve for \( x \):
\[
x = \frac{13}{\log(7)}
\]

### Step 4: Calculate the value of \( x \)
Now, compute the value of \( x \) using a calculator:
\[
x = \frac{13}{\log(7)} \approx \frac{13}{0.8451} \approx 15.3791
\]

So, the value of \( x \) rounded to four decimal places is \( \boxed{15.3791} \).
