3log42log45+log42=
To solve this problem, we'll follow these steps:
- Step 1: Combine the logarithms in the numerator.
- Step 2: Simplify the expression using logarithmic properties.
Now, let's work through each step:
Step 1: Combine the logarithms in the numerator using the sum of logarithms property:
log45+log42=log4(5×2)=log410.
Step 2: Simplify the entire expression 3log42log410:
3log42log410=log423log410=log48log410=log810.
This follows from the property that logbylogbx=logyx.
Therefore, the solution to the problem is log810.
