1. Problem Description

We need to solve the equation ln(x)+ln(6)=3\ln(x) + \ln(6) = 3 for xx, and give the answer correct to 3 decimal places.

2. Solution Steps

We can use the property of logarithms that ln(a)+ln(b)=ln(ab)\ln(a) + \ln(b) = \ln(ab). Therefore,
ln(x)+ln(6)=ln(6x)\ln(x) + \ln(6) = \ln(6x)
So, the equation becomes ln(6x)=3\ln(6x) = 3.
To solve for xx, we can exponentiate both sides with base ee:
eln(6x)=e3e^{\ln(6x)} = e^3
6x=e36x = e^3
Now, we can solve for xx by dividing both sides by 6:
x=e36x = \frac{e^3}{6}
We can approximate the value of e3e^3 as 20.

5. $x = \frac{20.0855}{6}$

x3.34758x \approx 3.34758
Rounding to 3 decimal places, we have x3.348x \approx 3.348.

3. Final Answer

x=e363.348x = \frac{e^3}{6} \approx 3.348
