Explicație pas cu pas:
media geometrica a doua numere = mg(a,b) = √(a·b)
a) a = 6 ; b = 8 => mg(6 ; 8) = √(6·8) = √48 = 4√3
b) a = 12 ; b = 7 => mg(12 ; 7) = √(12·7) = 2√21
c) a = 3/4 ; b = 2 => mg(3/4 ; 2) = √(3/4 ·2) = √(3/2) = √6 / 2
d) a = √56 ; b = √24 => mg(√56 ; √24) = √[√(56·24)] = √√1344=
= √(8√21) = 2√(2√21) = 2·2¹⁽²· 21¹⁽⁴
e) a = √2 ; b = √8 => mg(√2 ; √8) = √(√2·√8) = √(√16) = √4 = 2
f) a =√35 ; b = √124 => mg = √[√(35·124)] = 4340¹⁽⁴
