Răspuns:
[tex]\frac{x}{y} =2[/tex]
Explicație pas cu pas:
[tex]x=0,5=\frac{5}{10} ^{(5}=\frac{1}{2}[/tex]
[tex]y=0,25=\frac{25}{100} ^{(25}=\frac{1}{4}[/tex]
[tex]\implies\frac{x}{y} =\frac{0,5}{0,25} =\frac{\frac{1}{2} }{\frac{1}{4} }[/tex]
[tex]\implies\frac{x}{y} =\frac{1}{2} :\frac{1}{4} =\frac{1}{2} \cdot\frac{4}{1} =\frac{4}{2} =2[/tex]
