Answer

La solución de la ecuación \( \left(x^{3}-1\right)=-27 \) es \( x \approx -2.96 \).

Solution

Para resolver la ecuación \( \left(x^{3}-1\right)=-27 \), seguimos estos pasos: 1. **Reorganizar la ecuación**: Primero, sumamos 1 a ambos lados de la ecuación para aislar el término \( x^3 \). \[ x^{3} - 1 + 1 = -27 + 1 \] Esto simplifica a: \[ x^{3} = -26 \] 2. **Tomar la raíz cúbica**: Ahora, tomamos la raíz cúbica de ambos lados para resolver para \( x \). \[ x = \sqrt[3]{-26} \] 3. **Calcular la raíz cúbica**: Ahora calculamos \( \sqrt[3]{-26} \). Voy a realizar el cálculo de \( \sqrt[3]{-26} \). Calculate the value by following steps: - step0: Calculate: \(\left(-26\right)^{\frac{1}{3}}\) - step1: Evaluate the power: \(-26^{\frac{1}{3}}\) - step2: Transform the expression: \(-\sqrt[3]{26}\) La raíz cúbica de \(-26\) es: \[ x \approx -2.962496 \] Por lo tanto, la solución de la ecuación \( \left(x^{3}-1\right)=-27 \) es: \[ x \approx -2.96 \] Esto significa que el valor de \( x \) que satisface la ecuación es aproximadamente \(-2.96\).

Extra Insights

To solve the equation \( x^{3} - 1 = -27 \), we start by adding 1 to both sides to isolate the cubic term: \[ x^{3} = -26. \] Next, we find the cube root of both sides. The solution can be expressed as: \[ x = \sqrt[3]{-26}. \] This gives us one real root, which is approximately \( x \approx -2.962 \). If you're looking for complex roots, you can also express it in polar form and find the two additional complex roots, which can be fun if you enjoy exploring numbers in the complex plane!
