Question

(Radical din 5+1)+2(1+radical din 5)²+(radical din 6-3)(radicaldin 6+3)

Answer 1

pai trebuie sa aplici formulele:

(1+√5)=>(1²+2X1X√5)=>2√5+6

(√6+3)(√6-3)=> (√6²)-3²=>6-9=>-3

si apoi rezolvi exercitiul...:

√5+1 +2(2√5+6) +(-3)=>5√5+10=>5(√5+2)

Answer 2

Radical 5 +1 +2(1+2 radical 5+5)+6-9
Radical 5 +1+2(6+2radical5)+6-9
Radical 5 + 1 + 12 + 4 radical 5 + 6 - 9
5 radical 5 + 10
