(\partial)/(\partial x)(ln(xy)+ln(yz)+5ln(xz))

Soluzione

\frac{\partial}{\partial x} (ln (x y) + ln (yz) + 5 ln (x z))

\frac{6}{x}

Fasi della soluzione

\frac{\partial}{\partial x} (ln (x y) + ln (yz) + 5 ln (x z))

Semplifica

ln (x y) + ln (yz) + 5 ln (x z) : ln (x^{6} y^{2} z^{6})

= \frac{\partial}{\partial x} (ln (x^{6} y^{2} z^{6}))

Considera

y, z

come costanti

Applica la regola della catena:

\frac{1}{x ^{6} y ^{2} z ^{6}} \frac{\partial}{\partial x} (x^{6} y^{2} z^{6})

= \frac{1}{x ^{6} y ^{2} z ^{6}} \frac{\partial}{\partial x} (x^{6} y^{2} z^{6})

\frac{\partial}{\partial x} (x^{6} y^{2} z^{6}) = 6 y^{2} z^{6} x^{5}

= \frac{1}{x ^{6} y ^{2} z ^{6}} \cdot 6 y^{2} z^{6} x^{5}

Semplificare

\frac{1}{x ^{6} y ^{2} z ^{6}} \cdot 6 y^{2} z^{6} x^{5} : \frac{6}{x}

= \frac{6}{x}
