Consider the expression: \[ f(x) = \left( \frac{{3x^2 - 2x + 1}}{{x^3 + 5x^2 + 7x + 3}} \right)^2 \] We want to find the derivative of \( f(x) \) with respect to \( x \). Derivation: Using the chain rule of differentiation, we can find the derivative of \( f(x) \) step by step. Let's denote the numerator and denominator of the fraction as \( u(x) \) and \( v(x) \) respectively: \[ u(x) = 3x^2 - 2x + 1 \] \[ v(x) = x^3 + 5x^2 + 7x + 3 \] Applying the chain rule, we get: \[ f'(x) = 2 \left( \frac{{u(x)}}{{v(x)}} \right) \cdot \frac{{u'(x) \cdot v(x) - u(x) \cdot v'(x)}}{{v(x)^2}} \] where \( u'(x) \) and \( v'(x) \) are the derivatives of \( u(x) \) and \( v(x) \) respectively. Now, we can find \( u'(x) \) and \( v'(x) \) as follows: \[ u'(x) = 6x - 2 \] \[ v'(x) = 3x^2 + 10x + 7 \] Plugging these values back into the formula for \( f'(x) \), we get: \[ f'(x) = 2 \left( \frac{{3x^2 - 2x + 1}}{{x^3 + 5x^2 + 7x + 3}} \right) \cdot \frac{{6x - 2 \cdot (x^3 + 5x^2 + 7x + 3) + (3x^2 + §§V0(18,41,1)§§ x + 7)}}{{(x^3 + 5x^2 + 7x + 3)^2}} \] This is the derivative of \( f(x) \) with respect to \( x \) in its simplified form. §§V1(1,44,1)§§ \begin{flalign*} &(a) \quad \text{Berechne: } \int_{0}^{1} \frac{x^ 12 - 1}{\ln x} \, \mathrm{d}x && \\ &(b) \quad \text{Löse die Gleichung: } \sqrt{ 6 x-1}+\sqrt[ 9 ]{ 2 x-5}= 12 && \\ &(c) \quad \text{Berechne: } \frac{ 8 }{5} \times \left(\frac{ 12 }{4} + \frac{5}{6}\right) && \\ &(d) \quad \text{Löse die Ungleichung: } 4 x + 5 \geq 12 x - 2 && \\ &(e) \quad \text{Berechne: } \left(\frac{ 3 }{4}\right)^ 2 \cdot \left(\frac{ 6 }{ 12 }\right)^ 6 && \\ &(f) \quad \text{Löse die Gleichung: } \frac{ 2 x}{ 9 } - \frac{5}{ 6 } = \frac{x+4}{6} && \\ &(g) \quad \text{Berechne: } \sqrt{16} \cdot \left(\frac{ 8 }{ 6 }\right)^{- 8 } && \\ &(h) \quad \text{Löse das Gleichungssystem:} \\ &\quad\quad \begin{cases} 6 x - 12 y = 5 \\ 4x + y = 2 \end{cases} && \\ &(i) \quad \text{Berechne: } \frac{5}{8} - \left(\frac{1}{ 3 } - \frac{ 4 }{5}\right) && \\ &(j) \quad \text{Löse die Gleichung: } 8 ( 9 x - 1) = 4x + 5 &&\\ &(a12) \quad \text{Berechne: } \frac{ 6 }{4} \cdot \left(\frac{5}{6} + \frac{7}{8}\right) && \\ &(b12) \quad \text{Löse die Gleichung: } \frac{ 2 x- 9 }{4} - \frac{ 3 x+2}{ 4 } = \frac{x+1}{ 12 } && \\ &(c12) \quad \text{Berechne: } \sqrt[ 6 ]{\frac{ 2 7}{64}} && \\ &(d12) \quad \text{Löse das Gleichungssystem:} \\ &\quad\quad \begin{cases} 8 x + 9 y = 8 0 \\ 4x - y = 5 \end{cases} && \\ &(e 5 4 ) \quad \text{Berechne: } \left(\frac{5}{6}\right)^{- 4 } \cdot \left(\frac{7}{10}\right)^{- 5 } && \\ &(f12) \quad \text{Löse die Ungleichung: } \frac{ 8 x- 8 }{ 3 } > \frac{x+ 2 }{4} && \\ &(g12) \quad \text{Berechne: } \log_{ 2 } 8 + \log_{\frac{ 6 }{ 4 }} 16 && \\ &(h12) \quad \text{Löse die Gleichung: } \sqrt{ 4 x+ 2 } = \sqrt{ 6 x- 2 } && \\ &(i12) \quad \text{Berechne: } \sin\left(\frac{\pi}{4}\right) \cdot \cos\left(\frac{\pi}{6}\right) + \tan\left(\frac{\pi}{ 3 }\right) && \\ &(j12) \quad \text{Löse das Gleichungssystem:} \\ &a1) \quad \text{Berechne: } \frac{ 12 }{4} \cdot \left(\frac{5}{6} + \frac{7}{8}\right) && \\ &a2) \quad \text{Löse die Gleichung: } \frac{ 6 x- 9 }{4} - \frac{ 6 x+ 6 }{ 8 } = \frac{x+ 4 }{ 3 } && \\ &a3) \quad \text{Berechne: } \sqrt[3]{\frac{ 4 7}{64}} && \\ &a4) \quad \text{Löse das Gleichungssystem:} \\ &\quad\quad \begin{cases} 6 x + 9 y = 5 0 \\ 4x - y = 5 \end{cases} && \\ &a5) \quad \text{Berechne: } \left(\frac{5}{6}\right)^{-2} \cdot \left(\frac{7}{10}\right)^{-1} && \\ &a6) \quad \text{Löse die Ungleichung: } \frac{ 4 x- 3 }{ 6 } > \frac{x+ 8 }{4} && \\ &a7) \quad \text{Berechne: } \log_{2} 8 + \log_{\frac{ 2 }{ 6 }} 16 && \\ &a8) \quad \text{Löse die Gleichung: } \sqrt{ 6 x+ 9 } = \sqrt{ 6 x- 6 } && \\ &a9) \quad \text{Berechne: } \sin\left(\frac{\pi}{4}\right) \cdot \cos\left(\frac{\pi}{6}\right) + \tan\left(\frac{\pi}{ 9 }\right) && \\ &a10) \quad \text{Löse das Gleichungssystem:} \\ &\quad\quad \begin{cases} 2 x - y + z = 4 \\ x + 9 y - 8 z = - 3 \\ 12 x + y + 4z = 9 \end{cases} && \\ &(b1) \quad \text{Berechne: } \frac{5}{8} \cdot \left(\frac{ 6 }{4} + \frac{ 2 }{5}\right) && \\ &(b2) \quad \text{Löse die Gleichung: } 8 x^2 + 5x - 6 = 0 && \\ &(b3) \quad \text{Berechne: } \sqrt{144} && \\ &(b4) \quad \text{Löse das Gleichungssystem:} \\ &\quad\quad \begin{cases} 9 x - 2 y = 7 \\ 5x + 4y = 11 \end{cases} && \\ &(b5) \quad \text{Berechne: } \left(\frac{ 9 }{5}\right)^{-2} \cdot \left(\frac{4}{7}\right)^{- 6 } && \\ &(b6) \quad \text{Löse die Ungleichung: } \frac{ 8 x+ 7 }{ 12 } \geq \frac{x- 8 }{ 8 } && \\ &(b7) \quad \text{Berechne: } \log_{2} 3 2 + \log_{\frac{ 1 }{2}} 4 && \\ &(b8) \quad \text{Löse die Gleichung: } \sqrt{4x+ 1 } = \sqrt{5x- 4 } && \\ &(b9) \quad \text{Berechne: } \sin\left(\frac{\pi}{6}\right) \cdot \cos\left(\frac{\pi}{4}\right) + \tan\left(\frac{\pi}{ 6 }\right) && \\ \end{flalign*} using iTextSharp.text;
