Question

salut! ma ajutați va rog frumos ? ​

Answer 1

Răspuns:

b)

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

c)

$\sqrt{2 \frac{14}{25} } = \sqrt{ \frac{2 \times 25 + 14}{25} } = \sqrt{ \frac{64}{25} } = \frac{8}{5}$

d)

$\sqrt{ 1\frac{11}{25} } = \sqrt{ \frac{1 \times 25 + 11}{25} } = \sqrt{ \frac{36}{25} } = \frac{6}{5}$

e)

$\sqrt{3 \frac{6}{25} } = \sqrt{ \frac{3 \times 25 + 6}{25} } = \sqrt{ \frac{81}{25} } = \frac{9}{5}$

f)

$\sqrt{4 \frac{13}{36} } = \sqrt{ \frac{4 \times 36 + 13}{36} } = \sqrt{ \frac{157}{36} } = \frac{12.52}{6}$
