Answer 1

$\sqrt[3]{125}=5$
$\sqrt[3]{ -7^{3} } =-7$
$\sqrt[3]{64supra27} = 4supra3$
$\sqrt[3]{-1supra1000} =-1supra10$
$\sqrt{324}= 18$
$\sqrt{81supra121}=9supra11$
$\sqrt{444}= \sqrt{4*11}=2 \sqrt{111}$
$\sqrt{1supra169}= \sqrt{1^2supra13^2}=1supra13$
[tex] \sqrt{169}= \sqrt{13^2}=13 [/tex]
$\sqrt[3]{0,008}= \sqrt[3]{8supra1000}= \sqrt[3]{2^3supra10^3}=2supra10=1supra5$
$\sqrt{576supra676}= \sqrt{24^2supra26^2}=24*26=624$

Answer 2

a)$\sqrt[3]{125}= \sqrt[3]{5^3}=5$
b)$\sqrt[3]{-7^3}=-7$
c)$\sqrt[3]{ \frac{64}{27} }= \sqrt[3]{ \frac{4^3}{3^3} }= \frac{4}{3}$
d)$\sqrt[3]{ \frac{-1}{1000} }= \sqrt[3]{ \frac{-1}{10^3} } =- \frac{1}{10}$
e)$\sqrt{324} =18$
f)$\sqrt{ \frac{81}{121} }= \frac{9}{11}$
g)$\sqrt{484} =22$
h)$\sqrt{ \frac{1}{169} } = \frac{1}{13}$
i)$\sqrt{169}=13$
k)$\sqrt[3]{0,008}=0,2$
l)$\sqrt{} \frac{576}{676} \frac{24}{26}= \frac{12}{13}$
