Răspuns: [tex]\bf \dfrac{5}{3}[/tex]
Explicație pas cu pas:
Salutare!
[tex]\bf \sqrt{\dfrac{18}{50}} = \sqrt{\dfrac{18^{(2}}{50}} = \sqrt{\dfrac{9}{25}}= \sqrt{\dfrac{3^{2}}{5^{2}}}=\dfrac{3}{5}[/tex]
[tex]\boxed{\boxed{\bf TEORIE: (x)^{-1}=\dfrac{1}{x^{1}}}}[/tex]
[tex]\bf Inversul~ este:~ \dfrac{1}{\dfrac{3}{5}}=\dfrac{1}{1}:\dfrac{3}{5}=\dfrac{1}{1}\cdot\dfrac{5}{3}=\boxed{\bf \dfrac{5}{3}}[/tex]
