Simplifions au maximum l'écriture des nombres suivants :
[tex]C = \sqrt{\dfrac{63}{25}}[/tex]
[tex]C = \dfrac{\sqrt{63}}{\sqrt{25}}[/tex]
[tex]C = \dfrac{\sqrt{9 \times 7}}{\sqrt{{5}^{2}}}[/tex]
[tex]C = \dfrac{\sqrt{{3}^{2} \times 7}}{5}[/tex]
[tex]\green{\boxed{\blue{\boxed{\red{C = \dfrac{3 \sqrt{7}}{5}}}}}}[/tex]
------------------------
[tex]D = \sqrt{\dfrac{1}{100}}[/tex]
[tex]D = \dfrac{\sqrt{1}}{\sqrt{100}}[/tex]
[tex]D = \dfrac{1}{\sqrt{{10}^{2}}}[/tex]
[tex]\green{\boxed{\blue{\boxed{\red{D = \dfrac{1}{10}}}}}}[/tex]
