Question

a) √4/9
b) √9/81
c) √4/25

Answer 1

A) 2/3

B) 1/3

C) 2/5

Explicação passo-a-passo:

$a) \\ \sqrt{ \frac{4}{9} } \\ \frac{ \sqrt{4} }{9} \\ \frac{ \sqrt{ {2}^{2} } }{3 {}^{2} } \\ \frac{2}{3} \\ b) \\ \sqrt{ \frac{9}{81} } \\ \sqrt{ \frac{1}{9} } \\ \frac{1}{3} \\ c) \\ \sqrt{ \frac{4}{25} } \\ \frac{ \sqrt{4} }{ \sqrt{25} } \\ \frac{ \sqrt{2 {}^{2} } }{ \sqrt{5 {}^{2} } } \\ \frac{2}{5}$
