Question

vă rog ajutaţi-ma. ​

Answer 1

Răspuns:

Explicație pas cu pas:

(-5)²=25

8,(3)= 8 intregi si 3/9=(8 ori 9+3)/9=75/9

6 la puterea minus 2=1/6²=1/36

√9=3

deci exercitiul devine acum:

(25: 75/9 - 1/36 ori 18) ori (x+1)=3-3x

(25 ori 9/75  - 1/2) ori (x+1)=3-3x

(9/3-1/2) ori (x+1)= 3-3x

(3-1/2) ori(x+1)= 3-3x

( (6-1)/2 ) ori (x+1)=3-3x

5/2 ori (x+1)=3-3x

5x/2+5/2= 3-3x

5x/2+3x=3-5/2

(5x+6x)/2= (6-5)/2

11x/2=1/2=> 11x=1=>x=1/11
