Logarithms are one of the most important mathematical concepts that find application in various fields, including engineering, physics, and computer science. A logarithm is a mathematical function that helps in converting exponential expressions into simple arithmetic operations. Logarithmic tables are the tables that provide the values of logarithmic functions for different values of the input. In this article, we will discuss log table 1 to 10 in detail.
Logarithms are an essential concept in mathematics that represent the power to which a given base must be raised to produce a given number. They are widely used in various fields, such as science, engineering, and finance. In this article, we will provide an introduction to logarithms, including their definition, properties, and applications.
A logarithm is a mathematical operation that measures the power to which a given base must be raised to produce a given number. Mathematically, the logarithm of a number x with respect to a base b is defined as:
Log b(x) = y
Where,
b is the base, x is the number, and y is the power to which the base must be raised to produce x.
Logarithmic functions are a type of mathematical function that maps the input value to its logarithm with respect to a specific base. These functions are widely used in various fields such as engineering, physics, and finance. In this article, we will discuss the types of logarithmic functions.
The natural logarithmic function is defined as the logarithm of a number with base e, where e is a mathematical constant approximately equal to 2.71828. This function is denoted as ln(x), and it is the inverse function of the exponential function e^x. The natural logarithmic function has several important properties that make it useful in calculus and other branches of mathematics.
The common logarithmic function is defined as the logarithm of a number with a base of 10. This function is denoted as log(x), and it is widely used in engineering, physics, and other fields that deal with large numbers. The common logarithmic function is also known as the base-10 logarithmic function.
The binary logarithmic function is defined as the logarithm of a number with base 2. This function is denoted as log2(x), and it is widely used in computer science and information theory. The binary logarithmic function is also known as the base-2 logarithmic function.
The exponential logarithmic function is a special type of function that combines the properties of exponential and logarithmic functions. This function is defined as f(x) = e^(kx), where k is a constant. The exponential logarithmic function is useful in modelling certain physical phenomena, such as radioactive decay and population growth.
The hyperbolic logarithmic function is defined as the logarithm of a number with respect to a hyperbolic function. This function is denoted as ln(x+sqrt(x^2-1)), and it is useful in hyperbolic geometry and other branches of mathematics.
Logarithmic rules are a set of mathematical rules that govern the manipulation of logarithmic expressions. These rules are essential in simplifying and solving logarithmic equations. In this article, we will discuss some of the most common logarithmic rules.
The logarithmic power rule states that the logarithm of a number raised to a power is equal to the product of the power and the logarithm of the number. This rule can be expressed as:
logb(x^n) = n logb(x)
The logarithmic product rule states that the logarithm of the product of two numbers is equal to the sum of the logarithms of the individual numbers. This rule can be expressed as:
logb(xy) = logb(x) + logb(y)
The logarithmic quotient rule states that the logarithm of the quotient of two numbers is equal to the difference of the logarithms of the individual numbers. This rule can be expressed as:
logb(x/y) = logb(x) - logb(y)
The change of base rule states that the logarithm of a number in one base can be expressed in terms of the logarithm of the same number in another base. This rule can be expressed as:
Log c(x) = log b(x) / log b(c)
Where,
C, b and x are positive real numbers with b and c not equal to 1.
The logarithmic property of zero states that the logarithm of 1 is equal to 0. This rule can be expressed as:
Log b (1) = 0
The logarithmic property of one states that the logarithm of the base of a logarithmic function is equal to 1. This rule can be expressed as:
Log b (b) = 1

The purpose of a log table is to simplify complex calculations that involve logarithms. It helps mathematicians and engineers quickly find the logarithm of a number and perform mathematical operations efficiently.
The log of 1 to 10 is a list of logarithms of different numbers ranging from 1 to 10. The logarithm of 1 is 0, and the logarithm of 10 is 1. The logarithms of other numbers between 1 and 10 can be found in the log table.
To find the logarithm of a number using a log table, locate the row in the table that corresponds to the first two digits of the number. Then, find the column that corresponds to the last digit of the number. The number in the intersection of the row and column is the logarithm of the number.
An antilog table is a reference tool used to find the antilogarithm of a number. It contains a list of antilogarithms of different numbers, which can be used to solve complex mathematical problems.
To use an antilog table, locate the row in the table that corresponds to the first two digits of the antilogarithm. Then, find the column that corresponds to the last digit of the antilogarithm. The number in the intersection of the row and column is the antilogarithm.
The base of the log table is 10. This means that the logarithms listed in the table are base-10 logarithms.
The natural logarithm, represented by "ln", is a logarithm with base e, which is approximately equal to 2.718. Base-10 logarithm, represented by "log", is a logarithm with base 10. Both types of logarithms are used in mathematics and have different applications.
To convert a number from logarithmic to exponential form, raise the base to the power of the logarithm. For example, if log10(x) = 2, then x = 10^2 = 100.
Yes, arithmetic operations can be performed using log tables. By converting the numbers to logarithmic form, addition and subtraction can be performed by adding or subtracting the logarithms of the numbers, while multiplication and division can be performed by adding or subtracting the logarithms of the factors or divisors, respectively.
