Question

media aritmetica a numerelor 3 radical 5 si radical 180 este egala cu...
$3 \sqrt{} 5$
$\sqrt{} 180$
​

Answer 1

$\sqrt{180 } = 6 \sqrt{5}$

Explicație pas cu pas:

media aritmetica are formula

$\frac{x + y}{2}$

deci

$\frac{3 \sqrt{5} + 6 \sqrt{5} }{2} = \frac{9 \sqrt{5} }{2}$

Answer 2

180=5*6*6 => sqrt(180)=6sqrt(5)
Media aritmetica este: (a+b)/2=
=[(3+6)sqrt5]/2=
=[9sqrt(5)]/2=4.5sqrt(5)

Succes!
