Question

Calcule as raiz quadrada das frações:
$a) \: \sqrt \frac{4}{9} = \\ b) \sqrt{ \frac{4}{25} } = \\ c) \sqrt{ \frac{16}{49} }$
​

Answer 1

Resposta:

Explicação passo-a-passo:

V(4/9)

4= 2²

9 =3²

4/9 = (2/3)²

V(2/3)² =2/3 >>>>

b

V(4/25)

4 = 2²

25 =5²

4/25= (2/5)²

V(2/5)²  = 2/5  >>>> resposta

c

V( 16/49)

16 = 4²

49 = 7²

16/49 = (4/7)²

V(4/7)²  = 4/7 >>>>> resposta
