    Ta có : 

    \(\dfrac{2}{3}+\dfrac{m}{4}+\dfrac{n}{6}=6\Rightarrow\dfrac{m}{4}+\dfrac{n}{6}=5\dfrac{1}{3}\)

    => m/4 = 2/6 = 2/3

    m/4 = 16/3 : ( 3+2 ) x 2 = 32/15

    n/6 = 16/3-32/15 = 16/5

    => m x n = 32 x 16 = 512

    Ta có : 

    23+m4+n6=6⇒m4+n6=513

    => m/4 = 2/6 = 2/3

    m/4 = 16/3 : ( 3+2 ) x 2 = 32/15

    n/6 = 16/3-32/15 = 16/5

    => m x n = 32 x 16 = 512
