$x^{10}:x^7=x^3\ \ ,\ \ y^{13}:y^8=y^5\ \ ,\ \ z^{41}:z^{19}=z^{22}\ \ ,\ \ 35^{21}:35^9=35^{12}\ ,\\\\(1,8)^{14}:(1,8)^9=(1,8)^5=18,89568\ \ ,\ \ (0,8)^{50}:(0,8)^{31}=(0,8)^{19}}\ ,\\\\\Big(-\dfrac{1}{2}\Big)^{28}:\Big(-\dfrac{1}{2}\Big)^{20}=\Big(-\dfrac{1}{2}\Big)^8=\dfrac{1}{256}\\\\\Big(-\dfrac{17}{20}\Big)^{43}:\Big(-\dfrac{17}{20}\Big)^{26}=\Big(-\dfrac{17}{20}\Big)^{17}=-\Big(\dfrac{17}{20}\Big)^{17}=-\dfrac{17^{17}}{20^{17}}$

$\Big(-5\dfrac{4}{13}\Big)^{17}:\Big(-5\dfrac{4}{13}\Big)^8=\Big(-5\dfrac{4}{13}\Big)^{9}=-\Big(5\dfrac{4}{13}\Big)^8=-\Big(\dfrac{69}{13}\Big)^{9}=-\dfrac{69^9}{13^9}$
