- When do we use common logarithms and when do we use natural logarithms
3 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 example the equation $7^ {x-2} = 30$ in the lesson, you solve by rewriting the equation in logarithmic form $\log_7 30 = x-2$
- What algorithm is used by computers to calculate logarithms?
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 computers to calculate logarithms?
- Easy way to compute logarithms without a calculator?
I would need to be able to compute logarithms without using a calculator, just on paper The result should be a fraction so it is the most accurate For example I have seen this in math class calc
- logarithms - Dividing logs with same base - Mathematics Stack Exchange
Problem $\\dfrac{\\log125}{\\log25} = 1 5$ From my understanding, if two logs have the same base in a division, then the constants can simply be divided i e $125 25 = 5$ to result in ${\\log5} = 1 5$
- Multiplying two logarithms (Solved) - Mathematics Stack Exchange
I was wondering how one would multiply two logarithms together? Say, for example, that I had: $$\\log x·\\log 2x lt; 0$$ How would one solve this? And if it weren't possible, what would its doma
- logarithms - Log of a negative number - Mathematics Stack Exchange
For example, the following "proof" can be obtained if you're sloppy: \begin {align} e^ {\pi i} = -1 \implies (e^ {\pi i})^2 = (-1)^2 \text { (square both sides)}\\ \implies e^ {2\pi i} = 1 \text { (calculate the squares)}\\ \implies \log (e^ {2\pi i}) = \log (1) \text { (take the logarithm)}\\ \implies 2\pi i = 0 \text
