Impara online a risolvere i problemi di equazioni passo dopo passo. Solve the equation (2x-1)^2=49. Applicare la formula: x^a=b\to \left(x^a\right)^{\frac{1}{a}}=\pm b^{\frac{1}{a}}, dove a=2, b=49 e x=2x-1. Applicare la formula: a^b=a^b, dove a=49, b=\frac{1}{2} e a^b=\sqrt{49}. Applicare la formula: \left(x^a\right)^b=x, dove a=2, b=1, x^a^b=\sqrt{\left(2x-1\right)^2}, x=2x-1 e x^a=\left(2x-1\right)^2. Applicare la formula: x+a=b\to x=b-a, dove a=-1, b=\pm 7, x+a=b=2x-1=\pm 7, x=2x e x+a=2x-1.
