Объяснение:
а) f(x) = x¹² ; f'(x) = 12x¹¹
б) f(x) = -√5 х⁶ ; f'(x) = - 6√5x⁵
в) f(x)= 2x⁸ - 11x⁵ - 4x² + 26 ; f'(x) = 2*8х⁷ -11*5х⁴ + 4*2х = 16х⁷ - 55х⁴ +8х
г) f(x) = (x³-2) ∙ (x²+3); f’(x) = [(uv)’= uv’+u’v; u = x² +3; v=x³-2] =
(x³-2)(x²+3)’ + (x³-2)’(x²+3) = (x³-2)2x + (x²+3)3x² = 5x⁴ +9x² - 4x
д) f(x) = -x/(x² + 9)
