a)

324|2

162|2

81|3

27|3

9|3

3|3

 \mathsf{\sqrt{324}=\sqrt{{2}^{2}. {3}^{4}}}\\\mathsf{\sqrt{324}=2.{3}^{2}=2.9=18}

b)

64|2

32|2

16|2

8|2

4|2

2|2

1

 \mathsf{\sqrt[4]{64}=\sqrt[4]{{2}^{4}.2}=2\sqrt[4]{2}}

c)

 \mathsf{\sqrt{1000}=\sqrt[{10}^{2}. 10}=10\sqrt{10}}

d)

 \mathsf{\sqrt{0,25}=\sqrt{\dfrac{25}{100}}=\dfrac{5}{10}=0,5}

e)

 \mathsf{\sqrt{\dfrac{36}{49}}=\dfrac{6}{7}}

f)

 \mathsf{\sqrt[3]{\dfrac{8}{27}}=\dfrac{2}{3}}

g)

 \mathsf{\sqrt[3]{{3}^{5}+{3}^{5}+{3}^{5}}=\sqrt[3]{3.{3}^{5}}}\\\mathsf{\sqrt[3]{{3}^{6}}={3}^{2}=9}
