Introduce Numbers Log For Free

In Mathematics, logarithms are the other way of writing the exponents. A logarithm of a number with a base is equal to another number. A logarithm is just the opposite function of exponentiation. For example, if 102 = 100 then log10 100 = 2.

So log base 3 of 81 equals 4 andMoreAnd the 4 which was the exponent. Actually just stays down here. So log base 3 of 81 equals 4 and that's perfectly equivalent to this first equation. Hopefully that makes sense to everyone good.

Logarithms are the other way of expressing exponents. A logarithm is defined as the power to which a number must be raised to get some other values. In other words, it gives the answer to the question ?How many times a number is multiplied to get the other number??.

So, for logarithms I do the corresponding things: log3x asks "which exponent with base 3 gives us x?" f(x)=log3(x) is a one-to-one function, and y=f(x) has a graph of a certain shape. log3 is the inverse operation to exponentiation with base 3, so it's useful for undoing exponentiation with base 3.

The modern concept of the logarithm typically appears late in a second algebra or precalculus course (grades 10 or 11 in the US), situated after a study of polynomial and rational functions, but before sequences and series and conic sections.

In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3.

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.

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.

Log: (in math) An abbreviation for logarithm. logarithm: The power (or exponent) to which one base number must be raised ? multiplied by itself ? to produce another number. For instance, in the base 10 system, 10 must be multiplied by 10 to produce 100. So the logarithm of 100, in a base 10 system, is 2.
