Step-by-step Solution

Para calcular \( \log 22 \) utilizando la información dada, primero necesitamos entender que \( \operatorname{colog}(1/3) = x \) se refiere a la base del logaritmo. La función \( \operatorname{colog}(y) \) se refiere al logaritmo en base \( y \). Si \( \operatorname{colog}(1/3) = x \), esto significa que: \[ \log_{1/3}(x) = 1 \] Para calcular \( \log 22 \), podemos usar la propiedad de los logaritmos que dice que: \[ \log_a(b) = \frac{\log_c(b)}{\log_c(a)} \] donde \( c \) es cualquier base de logaritmo que elijamos. Usaremos la base 10 (logaritmo decimal) para simplificar el cálculo. Entonces, podemos escribir: \[ \log_{1/3}(22) = \frac{\log_{10}(22)}{\log_{10}(1/3)} \] Ahora, necesitamos calcular \( \log_{10}(22) \) y \( \log_{10}(1/3) \). 1. **Calcular \( \log_{10}(22) \)**: Usando una calculadora, encontramos que: \[ \log_{10}(22) \approx 1.3424 \] 2. **Calcular \( \log_{10}(1/3) \)**: Sabemos que \( \log_{10}(1/3) = \log_{10}(1) - \log_{10}(3) \). Como \( \log_{10}(1) = 0 \), tenemos: \[ \log_{10}(1/3) = -\log_{10}(3) \] Usando una calculadora, encontramos que: \[ \log_{10}(3) \approx 0.4771 \] Por lo tanto: \[ \log_{10}(1/3) \approx -0.4771 \] 3. **Sustituyendo en la fórmula**: Ahora podemos sustituir estos valores en la fórmula: \[ \log_{1/3}(22) = \frac{\log_{10}(22)}{\log_{10}(1/3)} \approx \frac{1.3424}{-0.4771} \approx -2.81 \] Por lo tanto, el valor de \( \log_{1/3}(22) \) es aproximadamente \( -2.81 \). Si necesitas el valor de \( \log 22 \) en otra base o más información, házmelo saber.

Quick Answer

Para calcular \( \log 22 \), primero se determina \( \operatorname{colog}(1/3) = x \) como \( \log_{1/3}(x) = 1 \). Luego, se usa la propiedad de los logaritmos para transformar \( \log_{1/3}(22) \) a base 10, resultando en aproximadamente \( -2.81 \).
