Question

Find dy/ dx when y= x ke power 4+12 x​

Answer 1

Question :-

• Find value of $\sf\dfrac{dy}{dx}$

Answer :-

• As we know we have to find $\sf\dfrac{dy}{dx}$ . For finding value of $\sf\dfrac{dy}{dx}$ we will have to differentiate both side with respect to x .

$\mapsto\sf{y = \ x^{4}+12x}$

Differentiating both side with respect to x we get

$\mapsto\sf{\dfrac{dy}{dx} = \dfrac{d}{dy}(\ x^{4}+12x)}$

$\mapsto\sf{\dfrac{dy}{dx} = 4\ x^{4-1}+12}$

$\mapsto\sf{\dfrac{dy}{dx} = 4\ x^{3}+12}$

• Hence , we easily got the value of $\sf\dfrac{dy}{dx}=4\ x^{3}+12$
