Impara online a risolvere i problemi di espressioni equivalenti passo dopo passo. (4-x^2-2xh-h^2)^(1/2)^2-(4-x^2)^(1/2)^2. Applicare la formula: \left(x^a\right)^b=x, dove a=\frac{1}{2}, b=2, x^a^b=\left(\sqrt{4-x^2-2xh-h^2}\right)^2, x=4-x^2-2xh-h^2 e x^a=\sqrt{4-x^2-2xh-h^2}. Applicare la formula: \left(x^a\right)^b=x, dove a=\frac{1}{2}, b=2, x^a^b=\left(\sqrt{4-x^2}\right)^2, x=4-x^2 e x^a=\sqrt{4-x^2}. Applicare la formula: -\left(a+b\right)=-a-b, dove a=4, b=-x^2, -1.0=-1 e a+b=4-x^2. Applicare la formula: a+b=a+b, dove a=4, b=-4 e a+b=4-x^2-2xh-h^2-4+x^2.
