b) √25/100

c) √121/144

d) √1/16

Answer 1

Explicação passo-a-passo:

Passe a raiz para o numerador e denominador, e calcule

a)

$\sf \sqrt{\dfrac{16}{9}} = \dfrac{\sqrt{16}}{\sqrt{9}} = \red{\dfrac{4}{3}}$

b)

$\sf \sqrt{\dfrac{25}{100}} = \dfrac{\sqrt{25}}{\sqrt{100}} = \red{\dfrac{5}{10}}$

c)

$\sf \sqrt{\dfrac{121}{144}} = \dfrac{\sqrt{121}}{\sqrt{144}} = \red{\dfrac{11}{12}}$

d)

$\sf \sqrt{\dfrac{1}{16}} = \dfrac{\sqrt{1}}{\sqrt{16}} = \red{\dfrac{1}{4}}$
