$$\frac{ 28 { c }^{ 2 } { d }^{ 2 } { e }^{ 2 } }{ 35c { e }^{ 4 } }$$
$\frac{4\times \left(\frac{d}{e}\right)^{2}}{5}$
$$\frac{\mathrm{d}}{\mathrm{d}c}(\frac{28e^{2}d^{2}}{35e^{4}}c^{2-1})$$
$$\frac{\mathrm{d}}{\mathrm{d}c}(\frac{4d^{2}}{5e^{2}}c^{1})$$
$$\frac{4d^{2}}{5e^{2}}c^{1-1}$$
$$\frac{4d^{2}}{5e^{2}}c^{0}$$
$$\frac{4d^{2}}{5e^{2}}\times 1$$
$$\frac{4d^{2}}{5e^{2}}$$
