Ребят, срочно,помогите решить все примеры подробно,прошу​

Answer 1

1) 5x^4

2) (-1/x - 3x)' = (-x^-1 - 3x)' = 1 - 3 = -2

3) 16x^3 + 1/2√x

4) x^2 - 1/√x - 5/x^2

5) (5x - 4)'(2x^4 - 7x + 1) + (5x - 4)(2x^4 - 7x + 1)' =

= 10x^4 - 35x + 5 + (5x - 4)(8x^3 - 7) =

= 10x^4 - 35x + 5 + 40x^4 - 35x - 32x^3 + 28 =

= 50x^4 - 32x^3 - 70x + 33

6) (x^3 - 7)'(3 - 4x^4) - (x^3 - 7)(3 - 4x^4)' =

= 3x^2(3 - 4x^4) + 16x^3(x^3 - 7) =

= 9x^2 - 12x^6 + 16x^6 - 112x^3 = - 112x^3 + 9x^2
