Question

a=25
b=9

ma/mg=? ............​

Answer 1

Răspuns:

Explicație pas cu pas:

Ma = (25+9)/2 = 34/2 = 17

Mg = √25×9 = √225 = 15

Ma/Mg = 17/15 = 1,1(3)

Answer 2

$\it \dfrac{m_a}{m_g}=\dfrac{\dfrac{a+b}{2}}{\sqrt{ab}}=\dfrac{a+b}{2\sqrt{ab}}=\dfrac{25+9}{2\sqrt{25\cdot9}}=\dfrac{\ \ 34^{(2}}{2\cdot5\cdot3}=\dfrac{17}{15}$
