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} = $

$\sqrt{81} + 9^2 =$

$\sqrt{36} + \sqrt{64} = 14$

$\sqrt{\dfrac{100}{4}} =5$

$7 + \sqrt{49}=14$

$\sqrt{9^2 + 81^2} =100$

$\sqrt{100} + 90 =100$

$\sqrt{\dfrac{128}{2}} + \dfrac{12}{2} =14$

$\sqrt{49} + \sqrt{\dfrac{32}{2}} =11$

$\sqrt{9^2 \times 81^2} =729$

$\sqrt{9 + 7}=4$

$\sqrt{25} - \sqrt{16} = 1$

$\sqrt{81} + 9^2 =90$
