  • 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 $\log_7 30 = x-2$
  • 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
  • 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?
  • Logarithms with negative bases for real numbers
    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
  • 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
  • Calculate logarithms by hand - Mathematics Stack Exchange
    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 and adding the negative of that log to the total You could probably use two soroban: one for the division, and one to accumulate the log
  • What is the point of logarithms? How are they used? [closed]
    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 population to double or for a bank balance to reach a given value with compound interest) Historically, they were also useful because of the fact that the logarithm of a product is the sum of the
