Learn how to solve problems step by step online. Find the derivative d/dx((4x)/((x^2+1)^2)). Wenden Sie die Formel an: \frac{d}{dx}\left(\frac{a}{b}\right)=\frac{\frac{d}{dx}\left(a\right)b-a\frac{d}{dx}\left(b\right)}{b^2}, wobei a=4x und b=\left(x^2+1\right)^2. Simplify \left(\left(x^2+1\right)^2\right)^2 using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 2 and n equals 2. Wenden Sie die Formel an: \frac{d}{dx}\left(nx\right)=n\frac{d}{dx}\left(x\right), wobei n=4. Wenden Sie die Formel an: \frac{d}{dx}\left(x\right)=1.
