Your expression seems to involve logarithms. Could you clarify the operation or write the expression with parentheses for better understanding? Here's how I currently interpret it:

$1.3 \log_2(x) + 2 \log_5(x) + 25 \log_3(x)$

Let me know if this is correct or if you would like to adjust it. If this is correct, I'll proceed with further analysis.

Do you want details or have any questions?

Here are 5 relative questions expanding on logarithmic concepts:

1. How do you simplify logarithmic expressions using logarithmic rules?
2. How do the properties of logarithms help in solving equations involving multiple bases?
3. What are some applications of logarithms in real-world scenarios, such as exponential decay?
4. How do you solve for $x$ when multiple logarithmic terms with different bases are involved?
5. What are the different methods to change the base of a logarithmic function?

Tip: The change of base formula allows you to convert logarithms to a common base for easier computation.
