Logaritmos y sus propiedades

Un logaritmo es simplemente otra forma de expresar una potencia. Por ejemplo, log₂ 8 = 3 significa que 2³ = 8. Cuando no se indica la base, se asume que es 10, y cuando usamos la base e (número irracional), se escribe como ln N.

Las propiedades de los logaritmos son claves para resolver problemas:

  1. El logaritmo de un número en su misma base es 1 logaa=1log_a a = 1
  2. El logaritmo de 1 en cualquier base es 0 loga1=0log_a 1 = 0
  3. El logaritmo de una potencia es el exponente multiplicado por el logaritmo de la base (log_a m^n = n·log_a m)
  4. El logaritmo de un producto es la suma de logaritmos (log_a (m·n) = log_a m + log_a n)
  5. El logaritmo de una división es la resta de logaritmos (log_a (m/n) = log_a m - log_a n)

💡 Truco práctico: Cuando veas un logaritmo, piensa siempre: "¿A qué exponente debo elevar la base para obtener ese número?" Así conectarás inmediatamente con la potencia correspondiente.

Para resolver ejercicios de logaritmos, normalmente convertirás la expresión logarítmica a una expresión exponencial. Por ejemplo, para calcular log₃ 9, piensas: "¿A qué exponente debo elevar 3 para obtener 9?". Como 3² = 9, entonces log₃ 9 = 2.

Recuerda que los logaritmos de números negativos no existen en los números reales, y que puedes aplicar las propiedades de potencias dentro de los logaritmos, como cuando trabajas con raíces (que son potencias fraccionarias).

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Los logaritmos son herramientas matemáticas fundamentales que permiten expresar potencias de forma diferente. Con la fórmula log_b N = x, estamos diciendo que b^x = N. Dominar los logaritmos y sus propiedades te permitirá resolver muchos problemas matemáticos con facilidad.
