26 Μαρ 2016 · Logarithms are simply another way to write exponents. Exponential and logarithmic functions are inverses of each other. For solving and graphing logarithmic functions (logs), remember this inverse relationship and you'll be solving logs in no time!
Introduction to Logarithms. In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number? Example: How many 2 s multiply together to make 8? Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2 s to get 8. So the logarithm is 3. How to Write it. We write it like this: log2(8) = 3.
The laws of logarithms are algebraic rules that allow for the simplification and rearrangement of logarithmic expressions. The 3 main logarithm laws are: The Product Law: log (mn) = log (m) + log (n). The Quotient Law: log (m/n) = log (m) – log (n). The Power Law: log (m k) = k·log (m).

4 Αυγ 2024 · Logarithm is a mathematical function that represents the exponent to which a fixed number, known as the base, must be raised to produce a given number. In other words, it is the inverse operation of exponentiation.
Logarithm formulas. = loga x () ay = x (a; x > 0; a 6= 1) loga 1 = 0. loga a = 1. loga(mn) = loga m + loga n. m. loga = loga m. n.
