Answer:
The equivalent expression of [tex]\ln(6\cdot a + 9\cdot b)[/tex] is [tex]\ln 3 + \ln (2\cdot a + 3\cdot b)[/tex].
Step-by-step explanation:
Let be [tex]r = \ln (6\cdot a + 9\cdot b)[/tex], which is now solved as follows:
1) [tex]\ln(6\cdot a + 9\cdot b)[/tex] Given.
2) [tex]\ln [3\cdot (2\cdot a + 3\cdot b)][/tex] Distributive property.
3) [tex]\ln 3 + \ln (2\cdot a + 3\cdot b)[/tex] ([tex]\ln (x\cdot y) = \ln x + \ln y[/tex]) Result.
The equivalent expression of [tex]\ln(6\cdot a + 9\cdot b)[/tex] is [tex]\ln 3 + \ln (2\cdot a + 3\cdot b)[/tex].
We want to find an equivalent expression to ln(6a + 9b). We will get:
ln(6a + 9b) = ln(3) + ln(2a + 3b)
Here we will be using the rule:
ln(x) + ln(y) = ln(x*y)
Now let's see our expression:
ln(6a + 9b) = ln(3*(2a + 9b))
Now we use the above rule to write:
ln(3*(2a + 3b)) = ln(3) + ln(2a + 3b)
Then the equivalent expression is:
ln(6a + 9b) = ln(3) + ln(2a + 3b)
