a)
[tex] \sqrt{25} = 5[/tex]
[tex]25 - 100\% \\ 5 - x \\ \\ x = \frac{5 \times 100\%}{25} = \frac{1 \times 100\%}{5} = 20\%[/tex]
Prawda
b)
[tex] \sqrt[3]{ \frac{1}{8} } = \frac{1}{2} [/tex]
[tex] \frac{1}{2} - 100\% \\ \frac{1}{8} - x \\ \\ x = \frac{ \frac{1}{8} \times 100 }{ 0.5} = \frac{1}{8} \times 200 = \frac{200}{8} = 25\%[/tex]
Prawda
