Question

Calculati media geometrica a numerelor a si b unde:
a) a=13 si b=52
b) a=√5 si b=45√5
c) a=222 si b=888
d)a=3(√5-1) si b=(√5+1)
Dau coroana!

Answer 1

a) mg=√13×52=26
b)mg=√45×5=15
c)mg=√222×888=444
d)mg=√3×4=2√3

Answer 2

a) a=13 si b=52
mg=√13*52=√676=26
b) a=√5 si b=45√5
mg=√(√5*45√5)=√5*45=5*3=15
c) a=222 si b=888
mg=√222*888=111*4=444
d)a=3(√5-1) si b=(√5+1)
mg=√3(√5-1)(√5-1)=√3(5-1)=√12=2√3
