Question

Exercitiul 4 punctele c d e, exercitiul 5 punctul c si exercitiul 6 punctul a c d , Vreau rezolvare completa (daca se poate) , mersi anticipat , dau coroana :)

Answer 1

(√5-2)(√5+2)-√(2-√3)(2+√3)=
(√5)²-4-(4-√3²)=5-4-4+3=0

(3√2-2√3)(3√2+2√3):(5√3-3√3)
(9*2-4*3):2√3=6:2√3=3:√3

(√2-√3-2√2+√3)(√2-√3+2√2-√3)*(6+2√6)+12
-√2*(3√2-2√3)*(6+2√6)+12=(-3*2+2√6)(6+2√6)+12=
-(6-2√6)(6+2√6)+12=
-(36-24)+12=-12+12=0

[1-√(2+√3)²]-[1-√(2-√3)²]=1-√(2+√3)²-1+√(2-√3)²=-2+√3+2-√3=0
