\frac{d}{d x} (x^{0.7} y^{0.3})

\frac{0.7 y ^{0.3}}{x ^{0.3}} + \frac{0.3 x ^{0.7} \frac{d y}{d x}}{y ^{0.7}}

Solution steps

\frac{d}{d x} (x^{0.7} y^{0.3})

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{0.7}, g = y^{0.3}

= \frac{d}{d x} (x^{0.7}) y^{0.3} + \frac{d}{d x} (y^{0.3}) x^{0.7}

\frac{d}{d x} (x^{0.7}) = \frac{0.7}{x ^{0.3}}

\frac{d}{d x} (y^{0.3}) = \frac{0.3 \frac{d y}{d x}}{y ^{0.7}}

= \frac{0.7}{x ^{0.3}} y^{0.3} + \frac{0.3 \frac{d y}{d x}}{y ^{0.7}} x^{0.7}

Simplify

\frac{0.7}{x ^{0.3}} y^{0.3} + \frac{0.3 \frac{d y}{d x}}{y ^{0.7}} x^{0.7} : \frac{0.7 y ^{0.3}}{x ^{0.3}} + \frac{0.3 x ^{0.7} \frac{d y}{d x}}{y ^{0.7}}

= \frac{0.7 y ^{0.3}}{x ^{0.3}} + \frac{0.3 x ^{0.7} \frac{d y}{d x}}{y ^{0.7}}

\frac{d}{d y} (3 cos (3 x) (x - y) + sin (3 x))

\frac{d}{d x} (\frac{4 x ^{4} + 7}{x ^{2}})

y^{^{'}} = 0.06 y - 0.0006 y^{2}

n = 1 \sum \infty \frac{n ^{3}}{n ^{3}}

\frac{d}{d x} (3 x^{3} - 2 x^{2} - 5 x + 2)
