What is a logarithm in one word?
A logarithm is a mathematical concept involving multiplication. A logarithm is the exponent that will yield a certain number. For a base of 3 to produce 9, the logarithm would be 2.
What logarithm means?
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.

Is logarithm a real word?
noun Mathematics. the exponent of the power to which a base number must be raised to equal a given number; log: 2 is the logarithm of 100 to the base 10 (2 = log10 100).
What is the root word for logarithm?
Napier coined the term for logarithm in Middle Latin, “logarithmus,” derived from the Greek, literally meaning, “ratio-number,” from logos “proportion, ratio, word” + arithmos “number”. The common logarithm of a number is the index of that power of ten which equals the number.
What is the use of logarithm?
A logarithm (or log) is the mathematical expression used to answer the question: How many times must one “base” number be multiplied by itself to get some other particular number? For instance, how many times must a base of 10 be multiplied by itself to get 1,000? The answer is 3 (1,000 = 10 × 10 × 10).
Why is it called a logarithm?
Logarithms were invented in the 17th century as a calculation tool by Scottish mathematician John Napier (1550 to 1617), who coined the term from the Greek words for ratio (logos) and number (arithmos).
Why do we use logarithm?
Logarithmic scales are useful for quantifying the relative change of a value as opposed to its absolute difference. Moreover, because the logarithmic function log(x) grows very slowly for large x, logarithmic scales are used to compress large-scale scientific data.
What is a synonym for exponential?

What does the Greek word log mean?
word
The Greek root word log means ‘word,’ and its variant suffix -logy means ‘study (of). ‘ Some common English words that use this root include biology, mythology, catalog, and prologue. Biology, of course, is the ‘study’ of life, whereas a prologue constitutes the ‘words’ spoken to introduce a poem or novel.
Why do we use logarithms?
It lets you work backwards through a calculation. It lets you undo exponential effects. Beyond just being an inverse operation, logarithms have a few specific properties that are quite useful in their own right: Logarithms are a convenient way to express large numbers.
What is exponential in simple words?
1 : of or relating to an exponent. 2 : involving a variable in an exponent 10x is an exponential expression. 3 : expressible or approximately expressible by an exponential function especially : characterized by or being an extremely rapid increase (as in size or extent) an exponential growth rate.
Is logarithmic the same as exponential?
Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. y = logax only under the following conditions: x = ay, a > 0, and a≠1.

What is exponential in maths?
exponential function, in mathematics, a relation of the form y = ax, with the independent variable x ranging over the entire real number line as the exponent of a positive number a. Probably the most important of the exponential functions is y = ex, sometimes written y = exp (x), in which e (2.7182818…)
