Question

Sa se calculeze media aritmetica a numerelor:
a) m=√3+√2 si n=√3-√2
b)m=3√5+4√3 si n=3√5-4√3
c)m=3√2+2√5 si n=2√5-3√2
d) m=√15+√16 si n=-√16+√15

Answer 1

a) m=√3+√2 si n=√3-√2
media = (√3+√2 + √3-√2) / 2 = 2√3  / 2 = √3

b)m=3√5+4√3 si n=3√5-4√3
media = (3√5+4√3 + 3√5-4√3) / 2 = 6√5 / 2 = 3√5

c)m=3√2+2√5 si n=2√5-3√2
media = (3√2+2√5 + 2√5-3√2) / 2 = 4√5 / 2 = 2√5

d) m=√15+√16 si n=-√16+√15
media = (√15+√16 -√16+√15) / 2 = 2√15 / 2 = √15
