Primero, multipliquemos los términos. \( \sqrt{5} \cdot 2\sqrt{15} = 2 \cdot \sqrt{5 \cdot 15} \). Sabemos que \( 5 \cdot 15 = 75 \), así que ahora tenemos \( 2\sqrt{75} \). Para simplificar \( \sqrt{75} \), podemos descomponerlo: \( 75 = 25 \cdot 3 \). Dado que \( \sqrt{25} = 5 \), podemos escribir \( \sqrt{75} = \sqrt{25 \cdot 3} = 5\sqrt{3} \). Así que, sustituyendo de nuevo, tenemos \( 2\sqrt{75} = 2 \cdot 5\sqrt{3} = 10\sqrt{3} \). ¡Y ahí lo tenemos! La respuesta simplificada es \( 10\sqrt{3} \).
