Answer 2

1)

A)

${6}^{3} = 6.6.6 = 216$

B)

${2}^{8} = 2.2.2.2.2.2.2.2 = 256$

C)

$\frac{ {4}^{2} }{ {3}^{5} } = \frac{4.4}{3.3.3.3.3} = \frac{16}{243}$

2)

A)

$\sqrt{81} =$

81 | 3

27 | 3

9 | 3

3 | 3

1

$\sqrt{ {3}^{2}. {3}^{2} } = 3.3 = 9$

B)

$\sqrt{36} =$

36 | 2

18 | 2

9 | 3

3 | 3

1

$\sqrt{ {2}^{2}. {3}^{2} } = 2.3 = 6$

C)

$\sqrt{144} =$

144 | 2

72 | 2

36 | 2

18 | 2

9 | 3

3 | 3

1

$\sqrt{ {2}^{2} . {2}^{2}. {3}^{2} } = 2.2.3 = 12$

D)

$\sqrt{ \frac{225}{169} } = \frac{ \sqrt{225} }{ \sqrt{169} }$

225 | 5

45 | 5

9 | 3

3 | 3

1

$\sqrt{ {5}^{2}. {3}^{2} } = 5.3 = 15$

169 | 13

13 | 13

1

$\sqrt{ {13}^{2} } = 13$

$resp... \: \: \frac{15}{13}$
