Question

(2√6+√54):√6-(8√5-√45):√5.

Answer 1

Scoatem factorii de sub radical

=> $(2\sqrt{6}+3\sqrt{6}):\sqrt{6}-(8\sqrt{5}-3\sqrt{5} ):\sqrt{5}$

Reducem termenii asemenea

=> $5\sqrt{6} :\sqrt{6} -5\sqrt{5} :\sqrt{5}$

Impartind orice expresie la ea insasi obtii rezultaul 1

=> 5 * 1 - 5 * 1 = 0

REZULTAT = 0
