miskamm [114]

Answer:

x = 12

Step-by-step explanation:

x - (-2) = 10 | Given

x - 2 = 10 | Distribute (whenever there is a minus on the outside of a parenthesis imagine a -1 on the outside, and flip the signs of everything on the inside)

x = 12 | Add 2 to both sides.

Find the derivative with respect to x of y = (3x + x^2)^5
RSB [31]
<h2>The required "option A) 5(3x + x^2)^{4} (3+2x)" is correct.</h2>

Step-by-step explanation:

We have,

y = (3x + x^2)^5          ..... (1)

To find, \dfrac{dy}{dx} = ?

Differentiating equation (1) w.r.t. 'x', we get

\dfrac{dy}{dx}= \dfrac{d[(3x + x^2)^5]}{dx}

⇒ \dfrac{dy}{dx}=5(3x + x^2)^{5-1} \dfrac{d(3x + x^2)}{dx}

[ ∵ y=x^{n} ⇒ \dfrac{dy}{dx}=nx^{n-1}]

⇒ \dfrac{dy}{dx}=5(3x + x^2)^{4} (3(1) + 2x^{2-1})

⇒ \dfrac{dy}{dx}=5(3x + x^2)^{4} (3+2x)

Thus, the required "option A) 5(3x + x^2)^{4} (3+2x)" is correct.
