Question

Resolver a equacao irracional 3√4x-2=2

Answer 1

3√(4x-2)=2  eleve ao quadrado os dois membros
(3√(4x-2))²=2²
3².(4x-2)=4
9.(4x-2)=4
36x-18=4
36x=4+18
36x=22
x=22/36
x=11/18

S{11/18}

Answer 2

 3√4x-2=2

 3√4x = 2+2 ==>  (3√4x-2)² = 2²

9.(4x-2) = 4 ==> 36x - 18 = 4

36x = 4+18 ==> 36x = 22

x =  22 ou x =  11
       36            18
