Question

2mn(n+k)/n-k при m=k=1/3, n=1/2

Answer 1

Ответ:

1 2/3

Пошаговое объяснение:

$\frac{2 \times \frac{1}{3} \times \frac{1}{2} ( \frac{1}{2} + \frac{1}{3} )}{ \frac{1}{2} - \frac{1}{3} } = \frac{ \frac{1}{3} ( \frac{3}{6} + \frac{2}{6}) }{ \frac{3}{6} - \frac{2}{6} } = \frac{ \frac{1}{3} \times \frac{5}{6} }{ \frac{1}{6} } = \frac{ \frac{5}{18} }{ \frac{1}{6} } = \frac{5}{18} \times 6 = \frac{5}{3} = 1\frac{2}{3}$
