Нужно найти производные функций

Решите задачу:

$y = ln(x) + 5 \\ \frac{d}{dx} ( ln(x) + 5) \\ \frac{d}{dx} ( ln(x) ) + \frac{d}{dx} (5) \\ \frac{1}{x} + 0 = \frac{1}{x} \\ y = log_{4}(x) + ln(x) \\ \frac{d}{dx} ( log_{2 {}^{2} }(x) + ln(x) ) \\ \frac{d}{dx} ( \frac{1}{2} \times log_{2}(x) + ln(x) ) \\ \frac{d}{dx} ( \frac{1}{2} \times log_{2}(x) ) + \frac{d}{dx} ( ln(x) ) \\ \frac{1}{2} \times \frac{1}{ ln(2)x } + \frac{1}{x} \\ \frac{1 + 2 ln(2) }{2 ln(2)x } \\ y = \sin(x) + x {}^{2} \\ \frac{d}{dx} ( \sin(x) ) + \frac{d}{dx} (x {}^{2} ) \\ \cos(x) + 2x \\ y = 5x {}^{3} + 4x - 6 \\ \frac{d}{dx} (5x {}^{3} ) + \frac{d}{dx} (4 x) - \frac{d}{dx} (6) \\ 5 \times 3x {}^{2} + 4 - 0 \\ 15x {}^{2} + 4$
