Impara online a risolvere i problemi di passo dopo passo. Solve the equation x^2+4y^2=4. Applicare la formula: x+a=b\to x=b-a, dove a=x^2, b=4, x+a=b=x^2+4y^2=4, x=4y^2 e x+a=x^2+4y^2. Applicare la formula: ax=b\to \frac{ax}{a}=\frac{b}{a}, dove a=4, b=4-x^2 e x=y^2. Applicare la formula: x^a=b\to \left(x^a\right)^{\frac{1}{a}}=\pm b^{\frac{1}{a}}, dove a=2, b=\frac{4-x^2}{4} e x=y. Applicare la formula: \left(x^a\right)^b=x, dove a=2, b=1, x^a^b=\sqrt{y^2}, x=y e x^a=y^2.
