Question

buna seara va rog ajutați-mă vreau rezolvari complete ​

Answer 1

$4 \sqrt{3} < \sqrt{n} < 5 \sqrt{2} \\ \sqrt{4 {}^{2} \times 3} < \sqrt{n} < \sqrt{5 {}^{2} \times 2} \\ \sqrt{16 \times 3} < \sqrt{n} < \sqrt{25 \times 2} \\ \sqrt{48} < \sqrt{n} < \sqrt{50} \\ \\ \sqrt{n} = \sqrt{49} \\ n = 49$

b)49
