Answer 1

Faça a fatoração do radicando

a) 549/3

183/3

61/61

1

$\sqrt{549} = \sqrt{ {3}^{2} \times 61 } = 3 \sqrt{61}$

b) 243/3

81/3

27/3

9/3

3/3

1

$\sqrt[3]{243} = \sqrt[3]{ {3}^{3} \times {3}^{2} } = \sqrt[3]{ {3}^{3} } \times \sqrt[3]{9} = 3 \sqrt[3]{9}$

c) 125/5

25/5

5/5

1

$\sqrt[5]{125} = \sqrt[3]{ {5}^{3} } = 5$

d) 256/2

128/2

64/2

32/2

16/2

8/2

4/2

2/2

1

$\sqrt[4]{256} = \sqrt[4]{ {2}^{4} \times {2}^{4} } = \sqrt[4]{ {2}^{4} } \times \sqrt[4]{ {2}^{4} } = 2 \times 2 = 4$
