Question

Найдите производную функции:
f(x)=(8x^5-5x^8)^12
f(x)=(4x^10-5x)^10
f(x)=(1/9-3x^3)^27
f(x)=(x^5-4x^4)^130

Answer 1

1) 12*(8x^5-5x^8)^11*(40x^4-40x^7)=480*x^(55)(8-5x^3)^11*x^4(1-x^3)=

480*x^(59)(8-5x^3)(^11)(1-x^3)

2) 10*(4x^10-5x)^9*(40x^9-5)=50*x^9(4x^9-5)^(9)*(8x^9-1)

3) 27(1/9-3x^3)^26*(-9x^2)=-x^2*(1/9-3x^3)^26*243

4)(x^5-4x^4)^129*(5x^4-4x^3)

Answer 2

$\f(x)=(8x^5-5x^8)^{12}\ f'(x)=12(8x^5-5x^8)^{11}(40x^4-40x^7)\ f'(x)=480x^{59}(8-5x^3)^{11}(1-x^3)\ f'(x)=480x^{59}(5x^3-8)^{11}(x^3-1)$

 

$\f(x)=(4x^{10}-5x)^{10}\ f'(x)=10(4x^{10}-5x)^9(40x^9-5)\ f'(x)=50x^9(4x^9-5)^9(8x^9-1)$

 

$\f(x)=(frac{1}{9}-3x^3)^{27}\ f'(x)=27(frac{1}{9}-3x^3)^{26}cdot(-9x^2)\ f'(x)=-243x^2(3x^3-frac{1}{9})^{26}$

 

$\f(x)=(x^5-4x^4)^{130} \ f'(x)=130(x^5-4x^4)^{129}(5x^4-16x^3)\ f'(x)=130x^{519}(x-4)^{129}(5x-16)$
