$\int_{- 5}^{3 x} \sqrt{15 - t} d t$

Step 1

Take the derivative of $\int_{- 5}^{3 x} \sqrt{15 - t} d t$ with respect to $x$ using Fundamental Theorem of Calculus and the chain rule.

$\frac{d}{d x} [3 x] \sqrt{15 - (3 x)}$

Step 2.1

Since $3$ is constant with respect to $x$ , the derivative of $3 x$ with respect to $x$ is $3 \frac{d}{d x} [x]$ .

$3 \frac{d}{d x} [x] \sqrt{15 - (3 x)}$

Step 2.2

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 1$ .

$3 \cdot 1 \sqrt{15 - (3 x)}$

Step 2.3

Multiply.
