(d^2)/(dx^2)(x^{6/7}+5x)

\frac{d ^{2}}{d x ^{2}} (x^{\frac{6}{7}} + 5 x)

- \frac{6}{49 x ^{\frac{8}{7}}}

Solution steps

\frac{d ^{2}}{d x ^{2}} (x^{\frac{6}{7}} + 5 x)

\frac{d}{d x} (x^{\frac{6}{7}} + 5 x) = \frac{6}{7 x ^{\frac{1}{7}}} + 5

= \frac{d}{d x} (\frac{6}{7 x ^{\frac{1}{7}}} + 5)

\frac{d}{d x} (\frac{6}{7 x ^{\frac{1}{7}}} + 5) = - \frac{6}{49 x ^{\frac{8}{7}}}

= - \frac{6}{49 x ^{\frac{8}{7}}}

y^{^{'}} = 1 + a y

\frac{d}{d x} (cos (5 x^{2} - 7 x) (10 x - 7))

x y^{^{'}} - 3 y = x^{3}

\int (- 4 x^{\frac{3}{2}} + 3 x^{\frac{2}{3}} - 4 x^{2}) d x

\frac{\partial}{\partial z} (sin (y))
