Question

Punctele d si e va rog !!!!!!

Answer 1

d)radical(11-6√2)+radical(9-4√2)-radical(3+2√2)=radical(3-√2)²+radical(2√2-1)²-
-radical(1+√2)²=3-√2+2√2-1-1-√2=1
e)radical(42-12√6)+radical(10+4√6)+radical(28-16√3)+radical(21-12√3)=
=radical(6-√6)²+radical(2+√6)²+radical(4-2√3)²+radical(2√3-3)²=
=6-√6+2+√6+4-2√3+2√3-3=9
