$$\mathrm{i}\mathrm{\setminus }\mathcal{R}=\{\mathrm{x}\in \mathbb{R}\mid \mathrm{x}=5^{\mathrm{k}},\mathrm{k}\in {\mathbb{Z}}^{+}\mathrm{and}1⩽\mathrm{k}⩽4\}$$$$\mathrm{ii}\mathrm{\setminus }\mathcal{R}=\{\mathrm{y}\in \mathbb{R}\mid \mathrm{y}=2\mathrm{m},\mathrm{m}\in {\mathbb{Z}}^{+}\mathrm{and}1⩽\mathrm{m}⩽5\}$$
