Explicație pas cu pas:
[tex](\sqrt{4-x^{2} } )`=\frac{1}{2\sqrt{4-x^{2} }} (4-x^{2})`=\frac{1}{2\sqrt{4-x^{2} }} (-2x)=\frac{-2x}{2\sqrt{4-x^{2} }} =\frac{-x}{\sqrt{4-x^{2} }} \\((\frac{x+1}{x})^{50}) ` =50(\frac{x+1}{x})^{49}(\frac{x+1}{x})`=50(\frac{x+1}{x})^{49}(\frac{-1}{x^{2} })=\frac{-50}{x^{2} }(\frac{x+1}{x})^{49}[/tex]
