log1.51 log5\log1.5\frac{1\text{ }}{\log5} $$$$

Solution

It seems like there was a formatting issue with your input. Could you please clarify the expression you're working with? Here's an assumption based on the partial expression you provided:

If you're trying to express something like log1.5\log 1.5 divided by log5\log 5, the correct mathematical expression would be:

log1.5log5\frac{\log 1.5}{\log 5}

This expression represents the logarithm of 1.5 in base 5 using the change of base formula. Here's how it works:

Step-by-Step Explanation:

  1. Change of Base Formula: The formula for changing the base of a logarithm is:

    logba=logcalogcb\log_b a = \frac{\log_c a}{\log_c b}

    where logba\log_b a is the logarithm of aa with base bb, and cc is a new base (commonly 10 or ee for natural logarithms).

  2. Apply to Your Expression: Here, log1.5log5\frac{\log 1.5}{\log 5} can be interpreted as log51.5\log_5 1.5, which means the logarithm of 1.5 with base 5.

Simplification (If Required):

The expression log51.5\log_5 1.5 doesn't simplify further without a calculator since it’s a specific value.

If you meant something else, feel free to clarify, and I'll assist you further.
