Impara online a risolvere i problemi di passo dopo passo. Solve the equation (3x-8)^2=81. Applicare la formula: x^a=b\to \left(x^a\right)^{\frac{1}{a}}=\pm b^{\frac{1}{a}}, dove a=2, b=81 e x=3x-8. Applicare la formula: a^b=a^b, dove a=81, b=\frac{1}{2} e a^b=\sqrt{81}. Applicare la formula: \left(x^a\right)^b=x, dove a=2, b=1, x^a^b=\sqrt{\left(3x-8\right)^2}, x=3x-8 e x^a=\left(3x-8\right)^2. Applicare la formula: x+a=b\to x=b-a, dove a=-8, b=\pm 9, x+a=b=3x-8=\pm 9, x=3x e x+a=3x-8.
