Question

Calcule as raíses quadradas:
 \sqrt144
$\sqrt400$
$\sqrt100$
$\sqrt625$
$\sqrt324$
$\sqrt1024$
$\sqrt529$
$\sqrt1225$

Answer 1

$\sqrt{400} = \sqrt{ 2^{4}. 5^{2} } =4.5=20$

$\sqrt{100} = \sqrt{ 2^{2}. 5^{2} } =2.5=10$

$\sqrt{625} = \sqrt{ 5^{4} } = 5^{2} =25$

$\sqrt{324} = \sqrt{ 2^{2}. 3^{4} } =2. 3^{2} =18$

$\sqrt{1024} = \sqrt{ 2^{10} } = 2^{5} =32$

$\sqrt{529} = \sqrt{ 23^{2} } =23$

$\sqrt{1225} = \sqrt{ 5^{2}. 7^{2} } =5.7=35$
