Question

Sa ordonați crescător numerele

Answer 1

Explicație pas cu pas:

$- \sqrt{9} < - \sqrt{5} < - \sqrt{4} \iff - 3 < - \sqrt{5} < - 2$

$\sqrt{1} < \sqrt{3} < \sqrt{4} \iff 1 < \sqrt{3} < 2$

=>

$- \sqrt{5} < - 2 < - 0.(6) < 0.1(6) < \sqrt{3}$

sau:

$- \sqrt{5} \approx - 2,23606...$

$\sqrt{3} \approx 1,73205...$

$- 2,23606... < - 2 < - 0.66666... < 0.16666... < 1,73205...$

=>

$- \sqrt{5} < - 2 < - 0.(6) < 0.1(6) < \sqrt{3}$
