Question

ПОМОГИТИ СРОЧНО !!!!!

Answer 1

Ответ:

$\sqrt{(\sqrt{7} - \sqrt{3})^{2} } - \sqrt{(2-\sqrt{7})^{2} } = |\sqrt{7} - \sqrt{3}|-|2-\sqrt{7}) = \sqrt{7} - \sqrt{3} - \sqrt{7} + 2 = -\sqrt{3} + 2$

Объяснение:

Answer 2

$\sqrt{(\sqrt{7}-\sqrt{3})^{2}} -\sqrt{(2-\sqrt{7})^{2}} =|\sqrt{7} -\sqrt{3}|-|2-\sqrt{7}|=\\\\=\sqrt{7} -\sqrt{3} -(\sqrt{7}-2)= \sqrt{7} -\sqrt{3} -\sqrt{7}+2=\boxed{2-\sqrt{3}}$
