Impara online a risolvere i problemi di equazioni passo dopo passo. (n+1/n)^2=5. Applicare la formula: x^a=b\to \left(x^a\right)^{\frac{1}{a}}=\pm b^{\frac{1}{a}}, dove a=2, b=5 e x=n+\frac{1}{n}. Applicare la formula: \left(x^a\right)^b=x, dove a=2, b=1, x^a^b=\sqrt{\left(n+\frac{1}{n}\right)^2}, x=n+\frac{1}{n} e x^a=\left(n+\frac{1}{n}\right)^2. Applicare la formula: x+a=b\to x=b-a, dove a=\frac{1}{n}, b=\pm \sqrt{5}, x+a=b=n+\frac{1}{n}=\pm \sqrt{5}, x=n e x+a=n+\frac{1}{n}. Applicare la formula: -\frac{b}{c}=\frac{expand\left(-b\right)}{c}, dove b=1 e c=n.
