Answer 1

Resposta:

a) √(25/36) =√(5²/6²) =√(5/6)²=5/6

b) √(100/81) =√(10²/9²) =√(10/9)²=10/9

c) √(147/3) =√(49) =7

d) -√(36/64) =-√(6²/8²) =-√(6/8)²=-6/8

e) √(2/50) =√(1/25) =√(1/5)²=1/5

c) √(2 1/4) =√(2+1/4) =√(8/4+1/4)==√(9/4)=√(3²/2²)=√(3/2)² =3/2

Answer 2

a)

$\frac{5}{6}$

b)

$\frac{10}{9}$

c)

$7$

d)

$- \frac{3}{4}$

e)

$\frac{1}{5}$

f)

$\frac{3}{2}$

Explicação passo-a-passo:

a)

$\sqrt{ \frac{25}{36} } = \sqrt{ {5}^{2 } } + \sqrt{ {6}^{2} } = \frac{5}{6}$

b)

$\sqrt{ \frac{100}{81} } = \sqrt{ {10}^{2} } + \sqrt{ \ {9}^{2} } = \frac{10}{9}$

c)

$\sqrt{ \frac{147}{3} } = \sqrt{49} = 7$

d)

$- \sqrt{ \frac{36}{64} } = - \sqrt{ \frac{9}{16} } = - \frac{3}{4}$

e)

$\sqrt{ \frac{2}{50} } = \sqrt{ \frac{1}{25} } = \frac{1}{5}$

f)

$\sqrt{2 \frac{1}{4} } = \sqrt{ \frac{9}{4} } = \frac{3}{2}$
