Answer 1

$\int (2 \cos(x) - 5 {x}^{4} + 3)dx = \int 2 \cos(x) dx - \int5 {x}^{4} dx + \\ +\int 3dx = 2 \sin(x) - 5 \frac{ {x}^{5} }{5} + 3x = 2 \sin(x) - {x}^{5} + 3x + C$

$\int (3 {e}^{x} - {x}^{3} - 4)dx = \int3 {e}^{x} dx - \int {x}^{3} dx - \\ - \int 4dx = 3 {e}^{x} - \frac{ {x}^{4} }{4} - 4x + C$
