Question

√288-√512-√648+√162.

Answer 1

$\sqrt{288} - \sqrt{512} - \sqrt{648} + \sqrt{162} = \\ \\ 12 \sqrt{2} - 16 \sqrt{2} - 18 \sqrt{2} + 9 \sqrt{2} = - 13 \sqrt{2}$

Answer 2

Cum nr date nu sunt patrate perfecte, acestea trebuie descompuse pt a-i calcula.
12√2-16√2-18√2+9√2=
Cum toti au √2, putem efectua calculele cu toti termenii.
=-13√2
