Evaluate the indefinite integral: $\int (5x^{\frac{2}{5}}+7x^{-\frac{3}{5}}+2)dx$

$\frac{25}{7}{x}^{\frac{5}{7}}+\frac{35}{2}{x}^{\frac{2}{5}}+2x+C$

$\frac{25}{7}{x}^{\frac{7}{5}}+35x^{\frac{2}{5}}+2x+C$

$\frac{25}{7}{x}^{\frac{7}{5}}+\frac{35}{2}{x}^{\frac{2}{5}}+2x+C$

$25x^{\frac{7}{5}}+35x^{\frac{2}{5}}+2x+C$
