logarithm
For a number x, the power to which a given base number must be raised in order to obtain x. Written \log_b x. For example, \log_{10} 1000 = 3 because 10^3 = 1000 and \log_2 16 = 4 because 2^4 = 16
It is helpful to think of "power " Thus 103 = 1000 and log (1000) = 3 This is another source of confusion in acid base balance and is responsible for the mistaken impression that the body maintains remarkably tight control over its hydrogen ion concentration (Blood pressure or pulse measured with a logarithmic notation would also appear remarkably stable) When the pH changes by 0 3 units, e g , from 7 4 to 7 1 the hydrogen ion concentration doubles (from 40 to 80 nmol/1 )
The inverse of exponentiation; for example, alogax = x (Remember that logarithm is an operation like addition or exponentiation )
An exponent used in mathematical equations to express the level of a variable quantity (or, the power to which a number must be raised to produce a specific result)
The inverse function of an exponential For example ln(ex)=x=eln(x), for x>0
For a number x, the power to which a given base number must be raised in order to obtain x. Written log_b x. For example, log_{10} 1000 = 3 because 10^3 = 1000
Exponent of the power to which it is necessary to raise a fixed number (the base) to produce the given number For example, the logarithm of 100 (base 10) is 2 because 102 equals 100
The exponent expressing the power to which a fixed number must be raised to produce a given number
One of a class of auxiliary numbers, devised by John Napier, of Merchiston, Scotland (1550-1617), to abridge arithmetical calculations, by the use of addition and subtraction in place of multiplication and division
Thus, the common logarithm of 100 (log 100) is 2, because 10^2 = 100. Logarithms to the base e, in which e = 2.71828..., called natural logarithms (ln), are especially useful in calculus. Logarithms were invented to simplify cumbersome calculations, since exponents can be added or subtracted to multiply or divide their bases. These processes have been further simplified by the incorporation of logarithmic functions into digital calculators and computers. See also John Napier
The exponent of the power to which a base number must be raised to equal a given number An example: 2 is the logarithm of 100 to the base 10 One can look at this way: 10 * 10 = 100, which is the same as 102, and 2 is the exponent referred to above (cfExponents and Logarithms Discussion and Trees as Data Structures Discussion)
the power to which a number is raised -- the exponent Example: log 10^2 = 2
In the equation a=bx, the logarithm base b of a provides the value of the exponent, logba=x The logarithm is the exponent that is put on b to give the value of a
The exponent that indicates the power to which a number must be raised to produce a given number For example: if B2 = N, the 2 is the logarithm of N (to the base B), or 102 =100 and log10 100 = 2 Also abbreviated to "log "
the exponent required to produce a given number
In mathematics, the logarithm of a number is a number that it can be represented by in order to make a difficult multiplication or division sum simpler. a number representing another number in a mathematical system so that complicated calculations can be done as simple addition (logarithmus, from logos ( LOGIC) + arithmos ). In mathematics, the power to which a base must be raised to yield a given number (e.g., the logarithm to the base 3 of 9, or log3 9, is 2, because 3^2 = 9). A common logarithm is a logarithm to the base
{i} power to which a base must be raised to produce a given number (Mathematics)
