Answer 1

1) f'(x) = 35x⁶ +1
2) f'(x) = -6/x⁴ -4x³ +1,5
3) f'(x)= (7ˣ)'*(3x +5x²) + 7ˣ *(3x +5x²)' = 7ˣ*ln7*(3x +5x²) + 7ˣ*(3 +10x)
4) f'(x) =( (7x⁶ +5)(x² +3x) - (x⁷ +5x +1)(2x +3) )/(х² +3х)²=
=(7х⁸ +21х⁷ +5х² +15х - 2х⁸ -3х⁷ -10х² -15х -2х -3)/(х² +3х)²=
=(5х⁸ +19х⁷ -5х² -17х -3)/(х¹ +3х)²
5)f'(x) = 8x(5x³ -1) + (4x² +1)*15x² = 40x⁴ -8x +60x⁴ +15x² =
= 100x⁴ +15x² -8x
6) f'(x) = 2/(2x +1)
