Answer 2

a.)

$\sqrt{\frac{1}{9} } =\frac{0,5}{3}$

$\sqrt{} \frac{81}{25} =\frac{9}{5}$

$\sqrt{\frac{169}{4} } =\frac{13}{2}$

$\sqrt{\frac{625}{289} }=\frac{25}{17}$

$\sqrt{} \frac{3}{300} =\frac{0,3}{17,32}$

b.)

$\sqrt{1} \frac{9}{16} =\sqrt{} \frac{25}{16} =\frac{5}{4}$

$\sqrt{2} \frac{1}{4} =\sqrt{} \frac{9}{4} =\frac{3}{2}$

$\sqrt{3\frac{13}{36} } =\sqrt{\frac{121}{36} } =\frac{11}{6}$

$\sqrt{4\frac{29}{49} } =\sqrt{\frac{225}{49} } =\frac{15}{7}$

$\sqrt{5\frac{29}{100} } =\sqrt{\frac{529}{100} } =\frac{23}{10}$

c.)

$\sqrt{0,81} =\sqrt{\frac{81}{100} } =\frac{9}{10}$

$\sqrt{0,16} =\sqrt{\frac{16}{100} } =\frac{4}{10}$

$\sqrt{1,96} =\sqrt{\frac{196}{100} } =\frac{14}{10}$

$\sqrt{4,41} =\sqrt{\frac{441}{100} } =\frac{21}{10}$

$\sqrt{20,25} =\sqrt{\frac{2025}{100} } =\frac{45}{10}$

d.)

$\sqrt{\frac{2^{4} }{3^{6} } } =\sqrt{\frac{16}{81} } =\frac{4}{9}$

Sper ca te-am ajutat!

P.S:La ultimele nu am mai stiut cum se face pt. ca sunt pe calculator facute!
