1. Problem Description

The problem is 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 are given the equation ln(x)+ln(6)=3\ln(x) + \ln(6) = 3.
Using the logarithm property ln(a)+ln(b)=ln(ab)\ln(a) + \ln(b) = \ln(ab), we can rewrite the equation as:
ln(6x)=3\ln(6x) = 3
To remove the natural logarithm, we can exponentiate both sides of the equation using the base ee:
eln(6x)=e3e^{\ln(6x)} = e^3
Since eln(y)=ye^{\ln(y)} = y, we have:
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 e3e^3 as 20.085520.0855 and then divide by 6:
x=20.085563.34758333...x = \frac{20.0855}{6} \approx 3.34758333...
Rounding the result to 3 decimal places, we get x3.348x \approx 3.348.

3. Final Answer

x=3.348x = 3.348
