Question

Ex. 27 va rog frumos

Answer 1

a) x = 8 -> radical(18/2) = radical(9) = 3 - apartine N

b) x = 0 -> radical(40/5) = radical(8) - apartine Q

c) x = 0 -> radical(120/20) = radical(6) - apartine Q

d) x = 1 -> radical(112/7) = radical(16) = 4 - apartine N

e) x = 4 -> radical(144/9) = radical(16) = 4 - Apartine N

f) x = 5 -> radical(15/3) = radical(5) - Apartine R\Q
