Răspuns :
√x+1=4 √x=3 x=9
√2x-x=-1 x(√2-1)=-1 x= -1/√2-1 rationalizezi prin √2 x=-√2
√x²=x deci x-3=1 x=4
√2x-x=-1 x(√2-1)=-1 x= -1/√2-1 rationalizezi prin √2 x=-√2
√x²=x deci x-3=1 x=4
√x+1=4 √x=3 x=9
√2x-x=-1 x(√2-1)=-1 x= -1/√2-1 rationalizezi prin √2 x=-√2
√x²=x deci x-3=1 x=4
Sper sa fie corect Succes!
