Aidez moi , je n'arrive pas à trouver le bon résultat SVP - 17/4 X (5/2 - 4/2)² = ? - 4 X (5-2) - 33 + 5/2 (8-6) = ? - 6 X (5/7)^3 + [ (6-1) X (7+3) -2 ] = ?

[tex]\dfrac{17}{4}\times(\dfrac{5}{2} - \dfrac{4}{2})^2 = \dfrac{17}{4}\times(\dfrac{1}{2})^2 = \dfrac{17}{4}\times\dfrac{1}{4}=\dfrac{17}{16}\\\\\\\boxed{\dfrac{17}{4}\times(\dfrac{5}{2} - \dfrac{4}{2})^2 =\dfrac{17}{16}}[/tex]

[tex]4 \times (5-2) - 33 + \dfrac{5}{2} (8-6)=4 \times 3 - 33 + \dfrac{5}{2} \times 2=12 - 33 + 5=-16\\\\\\\boxed{4 \times (5-2) - 33 + \dfrac{5}{2} (8-6)=-16}[/tex]

[tex]6 \times (\dfrac{5}{7})^3 + [ (6-1) \times(7+3) -2 ]=6 \times \dfrac{5^3}{7^3} + [ 5 \times10 -2 ]\\\\=6 \times \dfrac{125}{343} + [ 50 -2 ]\\\\=\dfrac{750}{343} + 48\\\\=\dfrac{750}{343} + \dfrac{48\times343}{343}\\\\=\dfrac{750}{343} + \dfrac{16464}{343}\\\\=\dfrac{17214}{343}[/tex]

[tex]\boxed{6 \times (\dfrac{5}{7})^3 + [ (6-1) \times(7+3) -2 ]=\dfrac{17214}{343}}[/tex]
