Step-by-step Solution

Para resolver la ecuación dada, primero simplifiquemos ambos lados de la ecuación: Dado que \( \frac{1}{27} = 3^{-3} \), podemos reescribir la ecuación como: \[ 3^{(x+\frac{1}{2})} = (3^{-3})^{7\times (x-2)} \] Ahora, simplifiquemos la expresión de la derecha: \[ (3^{-3})^{7\times (x-2)} = 3^{-21(x-2)} \] Por lo tanto, la ecuación se convierte en: \[ 3^{(x+\frac{1}{2})} = 3^{-21(x-2)} \] Dado que las bases son iguales, podemos igualar los exponentes: \[ x + \frac{1}{2} = -21(x-2) \] Ahora, resolvamos esta ecuación para encontrar el valor de \( x \). Solve the equation by following steps: - step0: Solve for \(x\): \(x+\frac{1}{2}=-21\left(x-2\right)\) - step1: Expand the expression: \(x+\frac{1}{2}=-21x+42\) - step2: Move the variable to the left side: \(x+\frac{1}{2}+21x=42\) - step3: Add the terms: \(22x+\frac{1}{2}=42\) - step4: Move the constant to the right side: \(22x=42-\frac{1}{2}\) - step5: Subtract the terms: \(22x=\frac{83}{2}\) - step6: Multiply by the reciprocal: \(22x\times \frac{1}{22}=\frac{83}{2}\times \frac{1}{22}\) - step7: Multiply: \(x=\frac{83}{44}\) La solución de la ecuación es \( x = \frac{83}{44} \) o \( x \approx 1.8863 \).

Quick Answer

La solución de la ecuación es \( x = \frac{83}{44} \) o \( x \approx 1.8863 \).
