(\partial)/(\partial x)(ln(x^6+y^7))

\frac{\partial}{\partial x} (ln (x^{6} + y^{7}))

\frac{6 x ^{5}}{x ^{6} + y ^{7}}

Solution steps

\frac{\partial}{\partial x} (ln (x^{6} + y^{7}))

Treat

y

as a constant

Apply the chain rule:

\frac{1}{x ^{6} + y ^{7}} \frac{\partial}{\partial x} (x^{6} + y^{7})

= \frac{1}{x ^{6} + y ^{7}} \frac{\partial}{\partial x} (x^{6} + y^{7})

\frac{\partial}{\partial x} (x^{6} + y^{7}) = 6 x^{5}

= \frac{1}{x ^{6} + y ^{7}} \cdot 6 x^{5}

Simplify

\frac{1}{x ^{6} + y ^{7}} \cdot 6 x^{5} : \frac{6 x ^{5}}{x ^{6} + y ^{7}}

= \frac{6 x ^{5}}{x ^{6} + y ^{7}}
