Question

z+0,(3)= 2 supra 3 pls urgent​

Answer 1

Răspuns:

Explicație pas cu pas:

z + 0,(3) = 2/3

0,(3)= (3/9)⁽³=(3:3)/(9:3) = 1/3

z + 1/3 = 2/3

z = 2/3 - 1/3

z =(2-1)/3

z = 1/3

Answer 2

$z+0,(3) = \dfrac{2}{3}\, \Big|\cdot 3$

$\Rightarrow 3z + 0,(9) = 2$

$\Rightarrow 3z+1 = 2$

$\Rightarrow 3z = 2-1$

$\Rightarrow 3z = 1$

$\Rightarrow \boxed{z = \dfrac{1}{3}}$
