Schritte zur Lösung

Apply the Taylor Formula

= \frac{1}{729} + \frac{\frac{d}{d x} ( ( x ^{2} + 9 ) ^{- 3} ) ( 0 )}{1 !} x + \frac{\frac{d ^{2}}{d x ^{2}} ( ( x ^{2} + 9 ) ^{- 3} ) ( 0 )}{2 !} x^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( ( x ^{2} + 9 ) ^{- 3} ) ( 0 )}{3 !} x^{3} + \dots

Evaluate Derivatives

= \frac{1}{729} + \frac{0}{1 !} x + \frac{- \frac{2}{2187}}{2 !} x^{2} + \frac{0}{3 !} x^{3} + \frac{\frac{16}{6561}}{4 !} x^{4} + \frac{0}{5 !} x^{5} + \frac{- \frac{800}{59049}}{6 !} x^{6} + \frac{0}{7 !} x^{7} + \frac{\frac{3968092800}{9 ^{11}}}{8 !} x^{8} + \dots
