Mar 19, 2026 · I disagree that a targeted source on discrete logarithms can be replaced by a source for finite fields. We can discuss discrete logarithms in any group as a partial function. Indeed, elliptic …

I think only some logarithms (e.g log to the base $10$) aren't defined for $0$ and negative numbers, is that right? I'm confused because on all the websites I've seen they say "logs are not defined for $0$ …

May 14, 2021 · Currently, in my math class, we are learning about logarithms. I understand that the common logarithm has a base of 10 and the natural has a base of e. But, when do we use them? For …

Logarithms are defined as the solutions to exponential equations and so are practically useful in any situation where one needs to solve such equations (such as finding how long it will take for a …

Apr 30, 2016 · I was wondering how one would multiply two logarithms together? Say, for example, that I had: $$\\log x·\\log 2x < 0$$ How would one solve this? And if it weren't possible, what would its …

The GNU C library, for example, uses a call to the fyl2x() assembler instruction, which means that logarithms are calculated directly from the hardware. So the question is: what algorithm is used by …

You could build a table of certain logarithms: 10^ (-1/2), 10^ (-1/4), etc. Twenty such entries would allow you to calculate logs to 5 places by multiplying your target number by the appropriate power of ten …

Oct 29, 2021 · It is in that scenario that I have always only understood logarithms as defined for positive numbers, although there seems to be solutions for negative bases. My apologies if that wasn't clear.

May 27, 2024 · Why roots aren't the inverse of exponentiation but logarithms? Ask Question Asked 1 year, 10 months ago Modified 1 year, 10 months ago

Dec 5, 2023 · Before then, many books had tables of base-$10$ logarithms in an appendix. Suppose you wanted the logarithm of $123$ The table gave you logarithms of numbers between $1$ and …
