Answer:

La escala temporal geológica, escala de tiempo geológico o tabla cronoestratigráfica internacional es el marco de referencia para representar los eventos de la historia de la Tierra y de la vida ordenados cronológicamente. Establece divisiones y subdivisiones de las rocas según su edad relativa y del tiempo absoluto transcurrido desde la formación de la Tierra hasta la actualidad, en una doble dimensión: estratigráfica (superposición de rocas) y cronológica (transcurso del tiempo). Estas divisiones están basadas principalmente en los cambios faunísticos observables en el registro fósil y han podido ser datadas con cierta precisión por métodos radiométricos. La escala compila y unifica los resultados del trabajo sobre geología histórica realizado durante varios siglos por naturalistas, geólogos, paleontólogos y otros muchos especialistas. Desde 1974 la elaboración formal de la escala se realiza por la Comisión Internacional de Estratigrafía de la Unión Internacional de Ciencias Geológicas y los cambios, tras algunos años de estudios y deliberaciones por subcomisiones específicas, han de ser ratificados en congresos mundiales.2​

The expression: Can you explain how to factor out the 1/3 from 2 in detail I am having trouble.
slava [35]

Answer:

Explanation:

If you multiply (x - k)(x + k), you get x^{2} + k*x - k*x - k^{2} which is equal to x^{2} -k^{2}. Now you can see that  \frac{1}{3} *x^{2}  - 2 must be equal to \frac{1}{3}*(x^{2}  - k^{2}) which is equal to \frac{1}{3}*x^{2}  - \frac{1}{3}*k^{2}. Now we just need to solve 2 = \frac{1}{3}*k^{2}. The final answer is k = +- \sqrt{6}.
