Question

1 }sa se calculeze
(-3/2 ;0] U ( -1;4}=

2} sa se determine a apartine R astfel incat
a] [a;3] u (2;5]= [-3;5]

9)sa se calculeze
a) [-3;5}- (2;8) =
b) [-4;6]-(-2;4)=
e) [-√2 ;3)-[4;6]
f) [√2 ;5]-{√2;8,(6)}

Answer 1

Răspuns:

(-3/2 ;0] U ( -1;4}= (-3/2,4]

a] [a;3] U (2;5]= [-3;5]

a= -3

a) [-3;5}-(2;8) = [-3,2]

b) [-4;6]-(-2;4) = {-4,-3,-2,4,5,6}

e) [-√2;3)-[4;6] = [-√2,3)

f) [√2 ;5]-{√2;8,(6)] = Ø
