Сопоставьте функции и их производные

f′(x)=52xf'\left(x\right)=\frac{5}{2\sqrt[]{x}}

f(x)=5x3f\left(x\right)=\frac{5}{x^3}

f′(x)=−5x2f'\left(x\right)=-\frac{5}{x^2}

f(x)=5xf\left(x\right)=5\sqrt[]{x}

f′(x)=15x2f'\left(x\right)=15x^2

f(x)=5xf\left(x\right)=\frac{5}{x}

f′(x)=5f'\left(x\right)=5

f(x)=5x3f\left(x\right)=5x^3

f′(x)=−15x4f'\left(x\right)=-\frac{15}{x^4}

f(x)=5xf\left(x\right)=5x

f′(x)=10x4+8x3f'\left(x\right)=10x^4+\frac{8}{x^3}

f′(x)=10x6−8x3f'\left(x\right)=10x^6-\frac{8}{x^3}

f′(x)=10x4−8x3f'\left(x\right)=10x^4-\frac{8}{x^3}

f′(x)=10x6+8xf'\left(x\right)=10x^6+\frac{8}{x}
