Exercice : Calcul mental
$\sqrt{36} + \sqrt{64} =$
$\sqrt{\dfrac{100}{4}} =$
$7 + \sqrt{49}=$
$\sqrt{9^2 + 81^2} =$
$\sqrt{100} + 90 =$
$\sqrt{\dfrac{128}{2}} + \dfrac{12}{2} =$
$\sqrt{49} + \sqrt{\dfrac{32}{2}} =$
$\sqrt{9^2 \times 81^2} =$
$\sqrt{9 + 7}=$
$\sqrt{25} - \sqrt{16} = $
$\sqrt{81} + 9^2 =$
$\sqrt{36} + \sqrt{64} = 14$
$\sqrt{\dfrac{100}{4}} =5$
$7 + \sqrt{49}=14$
$\sqrt{9^2 + 81^2} =100$
$\sqrt{100} + 90 =100$
$\sqrt{\dfrac{128}{2}} + \dfrac{12}{2} =14$
$\sqrt{49} + \sqrt{\dfrac{32}{2}} =11$
$\sqrt{9^2 \times 81^2} =729$
$\sqrt{9 + 7}=4$
$\sqrt{25} - \sqrt{16} = 1$
$\sqrt{81} + 9^2 =90$
