Question

6. Determinati multimile:
A={x€N | 3 < radical din x < 4}
B={x€N |-6< radical din x < -5}
C={x€N |10. 5<x² < 50. 1}
​.

Answer 1

a)x=3v5+2V2
y = 8V2 -5V5
x+y=305+212+802-575=10V2-2V5
x-y=315+212-812+505=805-602
b)x = 7v3-8
y=3v3 +716
x+y=7V3-8+3V3+716=10V3+716-8
x-y=703-8-303-716=413-8-776
C)x=2/2+313-515
y =405-313 +212
x+y=2V2+303-515+415-313+212=
442 - 15
x-y=2V2+313-505-405+303-212
6V3 - 975
