鈴 Olved Solve Explain Why A Logarithm Base Must Be Positive Numerade Unluckily for us, most calculators and computers will only evaluate logarithms of two bases: base 10 and base e. happily, this ends up not being a problem, as we’ll see soon that we can use a “change of base” formula to evaluate logarithms for other bases. The base of the logarithm b is positive because it is equal to the base of the exponent, which is positive by the definition of exponential functions (see section 5.1).
Answered Why Must The Base Of A Logarithm Be Bartleby It is for such reasons that we only consider logarithms with positive bases, as negative bases are not continuous and generally not useful. hope this insight makes sense and is somewhat helpful!. Video solution, solved step by step from our expert human educators: solve explain why a logarithm base must be positive. not your book? video answer: hello: everyone in this question. we are to tell why logs, so let's have a lot that is log x to the base, an pit. It is used to find the exponent to which a base must be raised to obtain a specific number. the standard formula is written as f (x) = logb(x), where 'b' is the base (b > 0, b ≠ 1) and 'x' is the argument, which must be a positive number (x > 0). A base of 0 would always result in 0, since 0 raised to anything is 0, and a base of 1 will always result in 1. therefore, the base of a logarithm has to be a positive number other than 1, mostly larger than 1.

Use the change of base formula: logbx=logcblogcx, where c is any convenient base. most often you choose c=10 or c=e so you can evaluate the expression on a calculator. The base of any logarithm must be greater than 0 and not = 1. if the value is not greater than 0, the logarithmic graph would not be continuous and it would have values that are not defined in the real number system. The number x must be positive (logs can only act on positive numbers). the log of a product is the sum of the logs; the log of a quotient is the difference of the logs; you can 'bring powers down'. The base of a logarithm must be a positive number not equal to 1 because logarithms represent the power to which the base is raised to obtain a number. additionally, the input must be positive since logarithms cannot apply to negative numbers in a real context.
