So, I am going into college as a math major with a concentration in secondary education, but despite how much I’ve learnt and understood, the one thing I’ve never been able to wrap my head around is logarithms and how they work, what they do, and things such as that. Anyone know a good way to explain it?
Extraneous questions:
what is *ln*?
What does a subscript after the log mean, especially if it’s not 10?
In: 0
Logarithms are the inverse of exponents, similar to how division is the inverse of multiplication.
If you have an exponent of the form x^y = z
Then the corresponding logarithm is
log(x) z=y
Basically you are asking how many times to I have to multiple x by itself to get z.
x is called the base of the logarithm. If it’s not specified it’s usually assumed to be base 10. The exception is the natural logarithm, usually abbreviated ‘ln’ instead of ‘log’. The natural logarithm use the mathematical constant e as it’s base.
