Answer 1

Resposta:

A) √324= 18

B) √256= 16

C) √441 = 21

Explicação passo-a-passo:

a)

$\sqrt{324}$

324| 2

162| 2

81| 3

27|3

9| 3

3| 3

1

$\sqrt{324} = \sqrt{ {2}^{2} \times {3}^{2} \times {3}^{2} } = \\ 18$

b)

$\sqrt{256}$

256| 2

128| 2

64| 2

32| 2

16| 2

8|2

4| 2

2| 2

$\sqrt{256} = \sqrt{ {2}^{2} \times 2^{2} \times {2}^{2} \times {2}^{2} } \\ 16$

C)

$\sqrt{441}$

441| 3

147| 3

49| 7

7| 7

1

$\sqrt{441} = \sqrt{ {3}^{2} \times {7}^{2} } \\ 21$
