Question

23. Calculeaza radacinile pătrate ale numerelor:
25/49
(2/3)⁴
0,25
1/2500
196/324​

Answer 1

$\sqrt{ \frac{25}{49} } = \frac{5}{7}$

$\sqrt{{( \frac{2}{3} )}^{4}} = \sqrt{\frac{ {2}^{4} }{ {3}^{4} }} = \sqrt{\frac{16}{81} } = \frac{4}{9}$

$\sqrt{0.25} = \sqrt{ \frac{25}{100} } = \frac{5}{10} = \frac{1}{2}$

$\sqrt{ \frac{1}{2500} } = \frac{1}{50}$

$\sqrt{ \frac{196}{324} } = \frac{14}{18} = \frac{7}{9}$
