1) √a - 1/2 √b - 2/3 √a - √ b= creo que esta mal copiado sale 2 √a-9 √6

                                                                                                                     6

2)√9x - √25x + 1/3 √36x = 3 √x- 5√x+1 (6) √x = 0

                                                                3

 

 

3) -2/3 √18 + 11 √2 - 1/5 √50= -2(3) + 11 √2 - 1(5) √2 = 8 √2

                                                          3                   5
