Question

Am nevoie de ajutor la calcul​

Answer 1

Răspuns:

Explicație pas cu pas:

(0,(3))²=( 3/9)²=(1/3)²= 1/9

4⁸/₉=(4*9+8)/9=44/9

-

n= 4/3-4/3 *( ³⁾4/3-1/9):44/9

n= 4/3-4/3*(12/9-1/9):44/9

n= 4/3-4/3*11/9:44/9

n= 4/3-44/27:44/9

n= 4/3-44/27*9/44

n= 4/3-1/3

n= 3/3

n=1

Answer 2

$\it0,(3)=\dfrac{\ 3^{(3}}{9}=\dfrac{1}{3}\\ \\ \\ n=\dfrac{4}{3}-\dfrac{4}{3}\cdot\Big(\dfrac{^{3)}4}{\ \ 3}-\dfrac{1}{9}\Big):\dfrac{44}{9}=\dfrac{4}{3}-\dfrac{\not4}{3}\cdot\dfrac{\not11}{\not9}\cdot\dfrac{\not9}{\not44}=\dfrac{4}{3}-\dfrac{1}{3}=\dfrac{3}{3}=1$
