Schritte zur Lösung

Apply the Taylor Formula

= \frac{1}{49} + \frac{\frac{d}{d x} ( \frac{1}{( 7 + x ) ^{2}} ) ( 0 )}{1 !} x + \frac{\frac{d ^{2}}{d x ^{2}} ( \frac{1}{( 7 + x ) ^{2}} ) ( 0 )}{2 !} x^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( \frac{1}{( 7 + x ) ^{2}} ) ( 0 )}{3 !} x^{3} + \dots

Evaluate Derivatives

= \frac{1}{49} + \frac{- \frac{2}{343}}{1 !} x + \frac{\frac{6}{2401}}{2 !} x^{2} + \frac{- \frac{24}{16807}}{3 !} x^{3} + \frac{\frac{120}{117649}}{4 !} x^{4} + \dots
