Penyelesaian - Derivative

Applying the product rule of derivatives.

$$\frac{d}{dx}[x\times e^{5x}]=\frac{d}{dx}\left[x\right]\times e^{5x}+x\times \frac{d}{dx}\left[e^{5x}\right]$$

The derivative of a variable with respect to itself is always equal to one.

$$\frac{d}{dx}\left[x\right]\times e^{5x}+x\times \frac{d}{dx}\left[e^{5x}\right]=1\times e^{5x}+x\times \frac{d}{dx}\left[e^{5x}\right]$$

$$1\times e^{5x}+x\times \frac{d}{dx}\left[e^{5x}\right]=1\times e^{5x}+x\times \left(e^{5x}\times \left(\frac{d}{dx}\left[5x\right]\times \ln \left(e\right)+\frac{5x}{e}\times \frac{d}{dx}\left[e\right]\right)\right)$$
