The log calculator (logarithm) calculates the value of a logarithm with an arbitrary base.
Applying logarithms to arithmetic computations.
| Rule or special case | Formula |
|---|---|
| Quotient | ln(x/y) = ln(x) − ln(y) |
| Log of power | ln(xy) = y * ln(x) |
| Log of e | ln(e) = 1 |
| Log of one | ln(1)=0 |

How do you calculate log without table?
Easiest way to find the log of any number without tables
- log 2 = 0.3010.
- log 3 = 0.4771.
- log 7 = 0.8451.
- log e = 0.693.
- Learn the above 4 logarithms.
- log (ab) = log a + log b -> first logarithm identity.
- log (a/b) = log a – log b -> second logarithm identity.
- log (a^b) = b loga -> third logarithm identity.
How do I find the value of log10?
In this article, let us discuss how to find the value of log 10 to the base 10 and base e in detail.
What is the Value of Log 10?
| Value of log10 10 | log10 10 = 1 |
|---|---|
| Value of loge10 | loge10 (ln 10) = 2.302585 |
How do I change log10 to log2?
We can solve by using split formula. ln(e) = log2/loge = 2.303log(2). log 2 in base e (natural log ) is converted to log 2 base 10 by multiplying it with 2.303.
Is log2 the same as LN?
The change of base formula does it. log2(x)=ln(x)/ln(2). The ratio of natural logarithm and log base 2 is natural logarithm of 2. The natural logarithm of a number is its logarithm to the base of mathematical constant e, where e is the irrational and transcendental number which approximately equal to 2.718281828459.
How do you do log in math?
logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.
How do you find the value of log 1?
Common Logarithms Function- The logarithm function with base 10 is known as Common Logarithms Function. It is expressed as log10.
Log Table 1 to 10 for Log Base 10.

| Log 1 | 0 |
| Log 2 | 0.3010 |
| Log 3 | 0.4771 |
| Log 4 | 0.6020 |
How do you find log 5 without a calculator?
Finding logarithms without using calculators
- log4=2log2.
- log5=1−log2.
- log6=log2+log3.
- log8=3log2 and.
- log9=2log3.
What is the value of log 1000a?

2 Answers. The answer is 3.
How do you solve log 13 without a log table?
13 = 1.3 * 10^1, so log (10) 13 = 1 + log (10) 1.3. Since log 1 = 0, and log 2 = . 3010 (when you were brought up on log tables, you remember some key values!) 1.3 is less than 1.414, so log 1.3 < 0.1505.

What does log2 mean in math?
binary logarithm
Log base 2 is also known as binary logarithm. It is denoted as (log2n). Log base 2 or binary logarithm is the logarithm to the base 2. It is the inverse function for the power of two functions. Binary logarithm is the power to which the number 2 must be raised in order to obtain the value of n.
What is 1n in math?
1 Answer. 1. 1. It is the natural logarithm. It is defined as lnx=logex.
What is e in log?
The natural logarithm, or logarithm to base e, is the inverse function to the natural exponential function.e is sometimes called Euler’s number, after the Swiss mathematician Leonhard Euler (not to be confused with γ, the Euler–Mascheroni constant, sometimes called simply Euler’s constant), or Napier’s constant.
Is ln a base 10?
ln is base e and log is base 10.
What does log stand for in math?
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because. 102 = 100.
Can you multiply logs?
Multiplication.Well, remember that logarithms are exponents, and when you multiply, you’re going to add the logarithms. The log of a product is the sum of the logs.
