$\dfrac{12^{5}}{14^{5}} \cdot \bigg(\dfrac{6}{7}\bigg)^{7} = \bigg(\dfrac{12}{14}\bigg)^{5} \cdot \bigg(\dfrac{6}{7}\bigg)^{7} = \bigg(\dfrac{6}{7}\bigg)^{5} \cdot \bigg(\dfrac{6}{7}\bigg)^{7} = \bigg(\dfrac{6}{7}\bigg)^{5+7} = \bf \bigg(\dfrac{6}{7}\bigg)^{12}$

$\dfrac{1}{32} \cdot \bigg(\dfrac{1}{2}\bigg)^{23} = \dfrac{1^{5}}{2^{5}} \cdot \bigg(\dfrac{1}{2}\bigg)^{23} = \bigg(\dfrac{1}{2}\bigg)^{5} \cdot \bigg(\dfrac{1}{2}\bigg)^{23} = \bigg(\dfrac{1}{2}\bigg)^{5+23} = \bf \bigg(\dfrac{1}{2}\bigg)^{28}$
