Question

calcule as raízes quadradas A)
$\sqrt{81 \sqrt{81} }$
B)
$\sqrt{36 \sqrt{36} }$
c)
$\sqrt{25 \sqrt{25} }$
d)
$\sqrt{64 \sqrt{64} }$
​

Answer 1

Resposta:

$A) \sqrt{81.9} =\sqrt{81} .\sqrt{9} =9.3=27\\ B)\sqrt{36.6}=\sqrt{36} .\sqrt{6} =6\sqrt{6}\\ C)\sqrt{25.5} =\sqrt{25} .\sqrt{5} =5\sqrt{5} \\ D)\sqrt{64.8} =\sqrt{64} .\sqrt{8} =8\sqrt{2.4} =8(\sqrt{2} .\sqrt{4} )=8(2\sqrt{2} )=16\sqrt{2}$
