To simplify the given expression, we can use the properties of logarithms. Specifically, we can use the properties:
ln(a)−ln(b)=ln(ba)
aln(b)=ln(ba)
ln(a)+ln(b)=ln(ab)
Using these properties, we can simplify the expression step by step.
Solution Approach
Apply the property ln(a)−ln(b)=ln(ba) to the term inside the first set of parentheses.
Apply the property aln(b)=ln(ba) to the term inside the second set of parentheses.
Combine the results using the properties of logarithms.
Step 1: Rewrite the Expression
We start with the expression:
2(ln(2x)−ln(y))−(ln(3)+2ln(5))
Step 2: Apply Logarithmic Properties
Using the properties of logarithms, we can rewrite the expression:
2(ln(2x)−ln(y))=2ln(2x)−2ln(y)=ln((2x)2)−ln(y2)=ln(y2(2x)2)
And for the second part:
−(ln(3)+2ln(5))=−ln(3)−ln(52)=−ln(3)−ln(25)=−ln(75)
Step 3: Combine the Results
Now we combine the two parts:
ln(y2(2x)2)−ln(75)=ln(75y2(2x)2)
Final Answer
Thus, the fully simplified expression is:
ln(75y24x2)
