Answer 1

Olá....

50.Efetue os cálculos:

a)

√49 = √7² = 7

b)

√81 = √9² = 9

c) √9/25 = √3²/5² = 3/5

d)

√81/64 = √9²/8² = 9/8

e)

√1/36 = √1/6² = 1/6

Espero ter ajudado.

Answer 2

A)

$\sqrt{49} \\ \sqrt{ {7}^{2} } \\ 7$

B)

$\sqrt{81} \\ \sqrt{ {9}^{2} } \\ 9$

C)

$\sqrt{ \frac{9}{25} }$

$\frac{ \sqrt{9} }{ \sqrt{25} }$

$\frac{ \sqrt{ {3}^{2} } }{ \sqrt{ {5}^{2} } }$

$\frac{3}{5}$

D)

$\sqrt{ \frac{81}{64} }$

$\frac{ \sqrt{81} }{ \sqrt{64} }$

$\frac{ \sqrt{ {9}^{2} } }{ \sqrt{ {8}^{2} } }$

$\frac{9}{8}$

E)

$\sqrt{ \frac{1}{36} }$

$\frac{ \sqrt{1} }{ \sqrt{36} }$

$\frac{1}{ \sqrt{ {6}^{2} } }$

$\frac{1}{6}$

F)

$\sqrt{ \frac{169}{121} }$

$\frac{ \sqrt{169} }{ \sqrt{121} }$

$\frac{ \sqrt{ {13}^{2} } }{ \sqrt{ {11}^{2} } }$

$\frac{13}{11}$
