Answer

La respuesta es \( 3^{3} \), que es opción C.

Solution

Para resolver la expresión \( 15^{3}: 5^{3} \), primero podemos simplificarla utilizando propiedades de las potencias. 1. **División de potencias**: La división de potencias con la misma base se puede simplificar restando los exponentes. Sin embargo, en este caso, tenemos bases diferentes, así que primero vamos a expresar \( 15 \) en términos de \( 5 \): \[ 15 = 3 \times 5 \] Por lo tanto, podemos reescribir \( 15^{3} \): \[ 15^{3} = (3 \times 5)^{3} = 3^{3} \times 5^{3} \] 2. **Sustitución en la expresión original**: Ahora sustituimos \( 15^{3} \) en la expresión original: \[ \frac{15^{3}}{5^{3}} = \frac{3^{3} \times 5^{3}}{5^{3}} \] 3. **Simplificación**: Al dividir \( 5^{3} \) entre \( 5^{3} \), se cancelan: \[ \frac{3^{3} \times 5^{3}}{5^{3}} = 3^{3} \] Por lo tanto, la respuesta es \( 3^{3} \). La opción correcta es **C \( 3^{3} \)**.

Extra Insights

To solve the expression \( 15^{3}: 5^{3} \), we can rewrite it as \( \frac{15^{3}}{5^{3}} \). By applying the property of exponents, we can simplify this to \( \left(\frac{15}{5}\right)^{3} = 3^{3} \). Therefore, the answer is C \( 3^{3} \). Now, let's dive into some fun insights! In ancient times, mathematicians used basic arithmetic and geometric principles to understand the world around them. Exponents, like the ones we're using, were common in their studies of area and volume, allowing them to advance knowledge in engineering and architecture. If you’re tackling problems involving exponents, always remember the “base game”: simplify your bases whenever possible! A common mistake is to overlook this and do complex calculations unnecessarily, which can lead to errors. Keep a keen eye on that base—it can save you loads of time!
