va eog frumos am nevoie de ajutor urgent
dau 5 stele și coroana ​

Answer 1

Explicație pas cu pas:

a)

$3 = \sqrt{9} \\ 2 \sqrt{2} = \sqrt{8}$

$\sqrt{9} > \sqrt{8} \implies 3 > 2 \sqrt{2}$

b)

$2 \sqrt{3} = \sqrt{12}$

$\sqrt{12} < \sqrt{13} \implies 2 \sqrt{3} < \sqrt{13}$

c)

$3 \sqrt{5} = \sqrt{45} \\ 2 \sqrt{11} = \sqrt{44}$

$\sqrt{45} > \sqrt{44} \implies 3 \sqrt{5} > 2 \sqrt{11}$

d)

$3 \sqrt{3} = \sqrt{27} \\ 2 \sqrt{6} = \sqrt{24}$

$\sqrt{27} > \sqrt{24} \implies 3 \sqrt{3} > 2 \sqrt{6}$

e)

$2 \sqrt{7} = \sqrt{28} \\ 4 \sqrt{2} = \sqrt{32}$

$\sqrt{28} < \sqrt{32} \implies 2 \sqrt{7} < 4 \sqrt{2}$

f)

$8 = \sqrt{64} \\ 2 \sqrt{15} = \sqrt{60}$

$\sqrt{64} > \sqrt{60} \implies 8 > 2 \sqrt{15}$

g)

$5 \sqrt{5} = \sqrt{125} \\ 8 \sqrt{2} = \sqrt{128}$

$\sqrt{125} < \sqrt{128} \iff 5 \sqrt{5} < 8 \sqrt{2}$

h)

$5 \sqrt{3} = \sqrt{75} \\ 4 \sqrt{5} = \sqrt{80}$

$\sqrt{75} < \sqrt{80} \implies 5 \sqrt{3} < 4 \sqrt{5}$
