Ответ:

1.

$f'(x) = 7 \times 4 {x}^{3} = 28 {x}^{3}$

2.

$f'(x) = - \frac{1}{21} \times( - 14) {x}^{ - 15} = \frac{2}{3 {x}^{15} }$

3.

$f'(x) = (5{x}^{ - 1} ) '= 5 \times ( - 1) {x}^{ - 2} = - \frac{5}{ {x}^{2} }$

4.

$f'(x) = (8 {x}^{ \frac{1}{2} } )' = 8 \times \frac{1}{2} {x}^{ - \frac{1}{2} } = \frac{4}{ \sqrt{x} }$

5.

$f'(x) = 0$

6.

$f'(x) = 50 {x}^{9} - 8 {x}^{7 } + 5 {x}^{4} + 8x - 3$

7.

$f'(x) = \frac{1}{ \cos {}^{2} ( x)} - \sin(x) - 0.2 \cos(x)$

8.

$f'(x) = - \frac{1}{ \sin {}^{2} (x) } + 15 {x}^{14} - \frac{1}{2 \sqrt{x} }$
