Question

(1) If Y = underroot 3x³ - 7x , then find dy/dx

(2) If Y = (ax^n + b)^p , then find dy/dx.

​

Answer 1

• In both questions, we use chain rule :

• If f(x) = f ( g (x))

then ,

=> f'(x) = f'g(x) × g'(x) .

•Formula used :

$\star \bold{ \frac{d}{dx} {x}^{n} = n {x}^{n - 1} } \\ \\ \star \bold{ \frac{d}{dx} \sqrt{x} = \frac{1}{2 \sqrt{x} } } \\ \\ \star \bold{ \frac{d}{dx} constant = 0}$
