Question

As respostas estão na foto mais eu quero os cálculos pfv mi ajudem ​

Answer 1

Vamos là.

a) √16/9 = √(4*4/3*3) = 4/3

b) √0,25 = √(1/4) = √(1/2*2) = 1/2  = 0,5

c) √(25/36) = √(5*5/6*6) = 5/6

d) √(1/4) = √(1/2*2) = 1/2

e) √(49/100) = √(7*7/10*10) = 7/10

f) √1,96 = √196/100 = √(14*14/10*10 = 14/10 = 1,4

Answer 2

Resposta:

$\sqrt{\frac{x}{y} } = \frac{\sqrt{x} }{\sqrt{x} }$

Usando a propriedade acima, temos:

a $\sqrt{\frac{16}{9} } = \frac{\sqrt{16} }{\sqrt{9} } =\frac{4}{3} \\\\\sqrt{0,25} = \sqrt{\frac{25}{100} } = \frac{\sqrt{25} }{\sqrt{100} } =\frac{5}{10} =0,5 \\\\\\\sqrt{\frac{25}{36} } = \frac{\sqrt{25} }{\sqrt{36} } =\frac{5}{6} \\\\\\\sqrt{\frac{1}{4} } = \frac{\sqrt{1} }{\sqrt{4} } =\frac{1}{2} \\\\\\\\\sqrt{\frac{49}{100} } = \frac{\sqrt{49} }{\sqrt{100} } =\frac{7}{10} \\\\\\\\\sqrt{1,96} = \sqrt{\frac{196}{100} } = \frac{\sqrt{196} }{\sqrt{100} } =\frac{14}{10} =1,4$
