Question

Calculati media aritmetica si media geometrica a numerelor √5-1 si √5+1

Answer 1

Ma = (√5 - 1 + √5 + 1) : 2 = (2√5) : 2 = √5

Mg = √(√5 - 1)(√5 + 1) = √(5 - 1) = √4 = 2

Answer 2

$ma = ( \sqrt{5} - 1 + \sqrt{5} + 1) \div 2 = (2 \sqrt{5} ) \div 2 = \sqrt{5}$
$mg = \sqrt{} ( \sqrt{5} - 1)( \sqrt{5} + 1) = \sqrt{} (5 - 1) = \sqrt{4} = 2$
