logarithm

log·a·rithm  (lôg-rm, lg-)

n. Mathematics

The power to which a base, such as 10, must be raised to produce a given number. If n^x = a, the logarithm of a, with n as the base, is x; symbolically, log_n a = x. For example, 10³ = 1,000; therefore, log₁₀ 1,000 = 3. The kinds most often used are the common logarithm (base 10), the natural logarithm (base e), and the binary logarithm (base 2).

logarithm [ˈlɒgəˌrɪðəm]

n

(Mathematics) the exponent indicating the power to which a fixed number, the base, must be raised to obtain a given number or variable. It is used esp to simplify multiplication and division: if a^x = M, then the logarithm of M to the base a (written log_aM) is x Often shortened to log See also common logarithm, natural logarithm

[from New Latin logarithmus, coined 1614 by John Napier (1550-1617), Scottish mathematician who invented them, from Greek, logos ratio, reckoning + arithmos number]

logarithm  (lôg-rthm)

The power to which a base must be raised to produce a given number. For example, if the base is 10, then the logarithm of 1,000 (written log 1,000 or log₁₀ 1,000) is 3 because 10³ = 1,000. See more at common logarithmnatural logarithm

(abbreviated tologlog) the number of times eg 10 must be multiplied by itself to produce a particular number 10  10  10 or 10³ = 1,000, so 3 is here the logarithm of 1,000. logaritme لوغاريثْم логаритъм logaritmus logaritme der Logarithmus λογάριθμος logaritmo logaritm لگاریتم logaritmi logarithme לוֹגָרִיתמִים लघुगणक logaritam logaritmus logaritma lógaritmi logaritmo 対数 로가리듬, 로그 logaritmas logaritms logaritma logaritme logaritme logarytm logaritmo logaritm логарифм logaritmus logaritem logaritam logaritm คณิตศาสตร์ลอการิทึม logaritma 對數 логаритм حساب کی سہولت کا ایک علم، لوگاردم hàm số loga 对数
