How do you write an equation for a logarithmic equation?
The power goes over here so the power is 5. So this number goes there so that’s log base 6 of 7776 equals 5 let’s try another one. So we have 5 to the third equals 125.
What is the formula of log a B?
log(a/b) = log a -log b, a > 0, b > 0. log an = n (log a) (Logarithm of a power). logx y = logmy / logmx (Change of base rule). logx y = 1 / logy x .
What are the 3 rules of logarithms?
Descriptions of Logarithm Rules. The logarithm of the product is the sum of the logarithms of the factors. The logarithm of the ratio of two quantities is the logarithm of the numerator minus the logarithm of the denominator. The logarithm of an exponential number is the exponent times the logarithm of the base.
What is log10 equal to?
The natural log function of 10 is denoted as “loge 10”. It is also known as the log function of 10 to the base e. The natural log of 10 is also represented as ln(10) The value of loge 10 is equal to 2.302585. loge 10 = ln (10) = 2.302585.

What are the 4 laws of logarithmic functions?
Logarithm Rules or Log Rules
- There are four following math logarithm formulas: ● Product Rule Law:
- loga (MN) = loga M + loga N. ● Quotient Rule Law:
- loga (M/N) = loga M – loga N. ● Power Rule Law:
- IogaMn = n Ioga M. ● Change of base Rule Law:
What is the first law of logarithm?
First Law. log A + log B = log AB. This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB.

Why are logarithms so hard?
The change of base part produced an extra step that was difficult to identify and deal with. Because the rules for logarithms are so suprising in a way, it is a bit like solving a puzzle where the steps in the puzzle are so entangled with themselves, that it becomes complicated to keep track of your moves…
