$$\int{\frac{\left(x - 3\right)^{6}}{49 x^{32}} d x} = - \frac{1}{1225 x^{25}} + \frac{9}{637 x^{26}} - \frac{5}{49 x^{27}} + \frac{135}{343 x^{28}} - \frac{1215}{1421 x^{29}} + \frac{243}{245 x^{30}} - \frac{729}{1519 x^{31}}$$

化简：

$$\int{\frac{\left(x - 3\right)^{6}}{49 x^{32}} d x} = \frac{- 81809 x^{6} + 1415925 x^{5} - 10226125 x^{4} + 39443625 x^{3} - 85687875 x^{2} + 99397935 x - 48095775}{100216025 x^{31}}$$

加上积分常数：

$$\int{\frac{\left(x - 3\right)^{6}}{49 x^{32}} d x} = \frac{- 81809 x^{6} + 1415925 x^{5} - 10226125 x^{4} + 39443625 x^{3} - 85687875 x^{2} + 99397935 x - 48095775}{100216025 x^{31}}+C$$

$$$\int \frac{\left(x - 3\right)^{6}}{49 x^{32}}\, dx = \frac{- 81809 x^{6} + 1415925 x^{5} - 10226125 x^{4} + 39443625 x^{3} - 85687875 x^{2} + 99397935 x - 48095775}{100216025 x^{31}} + C$$$A
