Question

Să se afle media aritmetica a divizorilor naturali ai nr 24.​

Answer 1

Salut,

$D_{24}⇒1, \: 2, \: 3, \: 4, \: 6, \: 8, \: 12, \: 24.$

Media Aritmetică:

( 1 + 2 + 3 + 4 + 6 + 8 + 12 + 24 ) ÷ 8 =
( 3 + 3 + 4 + 6 + 8 + 12 + 24 ) ÷ 8 =
( 6 + 4 + 6 + 8 + 12 + 24 ) ÷ 8 =
( 10 + 6 + 8 + 12 + 24 ) ÷ 8 =
( 16 + 8 + 12 + 24 ) ÷ 8 =
( 24 + 12 + 24 ) ÷ 8 =
( 36 + 24 ) ÷ 8 =
60 ÷ 8 =
$\boxed{\bold{7, 5}}$

Mult Succes !
