Question

Se considera numerele x={(-1/3)^10:(-1/3)^8*(-1/3)^-3}^-2 y=radical mare (2-radical5)^2+radical mare (radical5-3)^2+(-3)^2
a)Comparati numerele x si y
b) Calculati media aritmetica si media geometrica a numerelor x si y

Answer 1

a) x=3^12
y=10
x>y
b)Media geometrica =2305.3
Media aritmetica=256725.5
