Impara online a risolvere i problemi di equazioni passo dopo passo. Solve the equation (3z+a)^2=9. Applicare la formula: x^a=b\to \left(x^a\right)^{\frac{1}{a}}=\pm b^{\frac{1}{a}}, dove a=2, b=9 e x=3z+a. Applicare la formula: a^b=a^b, dove a=9, b=\frac{1}{2} e a^b=\sqrt{9}. Applicare la formula: \left(x^a\right)^b=x, dove a=2, b=1, x^a^b=\sqrt{\left(3z+a\right)^2}, x=3z+a e x^a=\left(3z+a\right)^2. Applicare la formula: x+a=b\to x=b-a, dove b=\pm 3, x+a=b=3z+a=\pm 3, x=3z e x+a=3z+a.
