Question

Найдите производную функции:
А)f(x)=$frac{2}{x} +4 x^{2}$
B) f(x)=$frac{1}{ x^{2} }- frac{6}{ x^{3} } +5$
D) f(x)=$x^{3} (6x+1)(2x-3)$

Answer 1

A
f`(x)=-2/x²+8x
B
f`(x)=-2/x³+18/x^4
D
f(x)=(6x^4+x³)(2x-3)
f`(x)=(24x³+3x²)(2x-3)+(6x^4+x³)*2=48x^4-72x³+6x³-9x²+12x^4+2x³=
=60x^4-64x³-9x²

Answer 2

Спасибо ОГРОМНОЕ)))
