Question

а)√6в)√3с)√5д)2√3​

Answer 1

Ответ: √6

Объяснение:

Пусть это выражение равно x. Тогда:

$x =\sqrt{2-\sqrt{3} } +\sqrt{2+\sqrt{3} }$

Возводим уравнение в квадрат:

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

Раскрывая по формуле, получаем. что:

$x^{2} =2-\sqrt{3} +2\sqrt{4-3} +2+\sqrt{3}$

Сокращаем противоположные и вычисляем:

$x^{2} =6$

x=√6
