Question

Vă rog, am mare nevoie! Vă implor! Am nevoie de rezolvarea completă! Dau 50 de puncte dacă e bun

Answer 1

a)
M.a.=(6+54)/2=30
M.g.=rad(6×54)=18 =>M.a.>M.g.
b)
M.a.=(1/4 + 1/9) × 1/2=13/72=aprox. 0,18
M.g.=rad(1/4 × 1/9)=1/6=aprox.0,16 =>M.a.>M.g.
c)
M.a.=(5+7,2)/2=6,1
M.g.=rad(5×7,2)=6 =>M.a.>M.g.
d)
M.a.=(28rad3+12rad3)/2=20rad3=aprox.34,64
M.g.=rad(28rad3×12rad3)=rad1008=aprox.31,75 =>M.a.>M.g.
e)
M.a.=(rad2+2rad2)/2=3rad2/2=aprox. 2,12
M.g.=rad(rad2×2rad2)=rad4=2 =>M.a.>M.g.
f)
M.a.=(8/7 + 3/125) × 1/2=(1000+21)/1750=aprox. 0,58
M.g.=rad(8/7 × 3/125)=rad24/875=aprox. 0,16 =>M.a.>M.g.
