You can convert to the same base, by the identity: logab = log b / log a (where the latter two logs are in any base, but both in the same base).

How do you change bases in algebra?

The answer depends on the context. The process for changing bases in logarithms is different to that for representing numbers in different bases - although the two are closely related.


Can logarithmic functions with different bases be combined into a single logarithm?

You can convert logarithms of different bases to the same base. After that, you may or may not be able to simplify the resulting expression. Example of change-of-base: log21024 = ln(1024) / ln(2) Instead of natural logarithms, you can convert to any other base: log21024 = log10(1024) / log10(2)


What does the word base mean in mathematics?

Unfortunately, there are many different meanings that depend on the context. Bases are used in plane geometry, solid geometry, number theory, logarithms and exponents and usually mean different things in each of these areas.


What is the difference between comparing exponential numbers with like bases and comparing those with unlike bases?

When comparing exponential numbers with like bases, the comparison is straightforward: one can directly compare the exponents to determine which value is larger. For example, with the same base (a), (a^m) is greater than (a^n) if (m > n). In contrast, when dealing with unlike bases, one must either convert the numbers to a common base or use logarithms to compare them effectively, as the relationship between the bases complicates the direct comparison of their exponents. This can lead to more complex calculations and considerations of the base values themselves.

What is the change of base formula?

In math, that may either refer to changing the base of the number system (for example, change from decimal (base 10) to binary (base 2)); or it may refer to changing logarithms, from one base to another - for example, common (base-10) logarithms to natural (base-e) logarithms.


Why were logarithms invented?

Logarithms were invented by John Napier who was a mathematician. He invented other things too, so there was no reason why he couldn't invent the logarithms. Logarithms were invented so people could take short cuts to multiplications! :)


How do you do logarithm with ln?

To calculate a logarithm using the natural logarithm (ln), you can use the relationship between logarithms of different bases. The natural logarithm is specifically the logarithm to the base (e), where (e \approx 2.71828). To convert a logarithm of another base (b) to natural logarithm, you can use the formula: (\log_b(x) = \frac{\ln(x)}{\ln(b)}). This allows you to compute logarithms in any base using the natural logarithm.
