To combine the expression 3 ln x + 2 ln c into a single natural logarithm, we can use the properties of logarithms.
The key properties we will use are:
- n ln a = ln an – This means we can rewrite a coefficient in front of the logarithm as an exponent.
- ln a + ln b = ln(ab) – This allows us to combine two logarithms by multiplying their arguments.
Applying these properties step by step:
- First, rewrite 3 ln x as ln(x3):
- 3 ln x = ln(x3)
- Next, rewrite 2 ln c as ln(c2):
- 2 ln c = ln(c2)
Now the expression becomes:
ln(x3) + ln(c2)
Using the second property to combine these, we have:
ln(x3) + ln(c2) = ln(x3 * c2)
Thus, the expression 3 ln x + 2 ln c can be written as a single natural logarithm:
ln(x3 * c2)
