**Log calculator** find the logarithm function an outcome (can be dubbed exponent) native the given base number and also a genuine number.

You are watching: Log base 3 of 1/3

**b: ** log in base number, b>0 and also b≠1 / **x: ** is real number, x>0

**logb(x) = y**, and **x = logb(bx)****logb(x) = y** and also **x = by**

## Logarithm

**Logarithm** is thought about to be one of the straightforward concepts in mathematics.There are plenty the definitions, beginning from really complex and ending up v rather basic ones.In order to answer a question, what a logarithm is, let"s take a look at the table below:

21 | 22 | 23 | 24 | 25 | 26 |

2 | 4 | 8 | 16 | 32 | 64 |

This is the table in which we deserve to see the worths of 2 squared, 2 cubed, and also so on.This is an procedure in mathematics, recognized as **exponentiation**.If us look at the number at the bottom line, we can try to find the power value to i m sorry 2 have to be raised to acquire this number.For example, to obtain 16, it is important to raise 2 to the fourth power.And to acquire a 64, you need to raise 2 to the sixth power.

Therefore, **logarithm is the exponent come which it is vital to advanced a fixed number** (which is called the base), to get the number y.In other words, a logarithm have the right to be stood for as the following:

logb x = y

with b being the base, x being a real number, and y being an exponent.

For example, 23 = 8 ⇒ log2 8 = 3 (the logarithm of 8 to basic 2 is same to 3, due to the fact that 23 = 8).Similarly, log2 64 = 6, because 26 = 64.

Therefore, it is noticeable that **logarithm procedure is an train station one to exponentiation**.

21 | 22 | 23 | 24 | 25 | 26 |

2 | 4 | 8 | 16 | 32 | 64 |

log22 = 1 | log24 = 2 | log28 = 3 | log216 = 4 | log232 = 5 | log264 = 6 |

Unfortunately, no all logarithms can be calculated that easily.For example, recognize log2 5 is hardly possible by just using our simple calculation abilities.After making use of logarithm calculator, us can find out that

log2 5 = 2,32192809

There room a couple of specific types of logarithms.For example, the logarithm to base 2 is known as the binary logarithm,and the is widely offered in computer system science and programming languages.The logarithm to base 10 is usually referred to as the common logarithm,and it has actually a huge number of applications in engineering, clinical research, technology, etc.Finally, so called natural logarithm provides the number e (which is around equal to 2.71828) together its base,and this kind of logarithm has a good importance in mathematics, physics,and other an accurate sciences.

The **logarithm** logb(x) = y is check out as log base b that x is equals to y.Please keep in mind that the **base of log** number b need to be higher than 0 and also must not be same to 1.And the number (x) i beg your pardon we room calculating **log** basic of (b) should be a hopeful real number.
