integral of 7x^{2/5}+3x^{-4/5}

\int 7 x^{\frac{2}{5}} + 3 x^{- \frac{4}{5}} d x

5 x^{\frac{7}{5}} + 15 x^{\frac{1}{5}} + C

Solution steps

\int 7 x^{\frac{2}{5}} + 3 x^{- \frac{4}{5}} d x

3 x^{- \frac{4}{5}} = \frac{3}{x ^{\frac{4}{5}}}

= \int 7 x^{\frac{2}{5}} + \frac{3}{x ^{\frac{4}{5}}} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 7 x^{\frac{2}{5}} d x + \int \frac{3}{x ^{\frac{4}{5}}} d x

\int 7 x^{\frac{2}{5}} d x = 5 x^{\frac{7}{5}}

\int \frac{3}{x ^{\frac{4}{5}}} d x = 15 x^{\frac{1}{5}}

= 5 x^{\frac{7}{5}} + 15 x^{\frac{1}{5}}

Add a constant to the solution

= 5 x^{\frac{7}{5}} + 15 x^{\frac{1}{5}} + C

y^{^{'''}} - 5 y^{^{''}} + 3 y^{^{'}} + 9 y = 0

x \to - 10 lim (- 15)

\frac{d}{d x} (x, π x)

\frac{10}{1 + e ^{- x}}

\int \frac{1}{x ^{2} ( 2 x - 1 )} d x
