$x^{2} y^{3 - x^{3} + y + 2}$

Step 1

Add $3$ and $2$ .

$\frac{d}{d x} [x^{2} y^{- x^{3} + y + 5}]$

Step 2

Differentiate using the Product Rule which states that $\frac{d}{d x} [f (x) g (x)]$ is $f (x) \frac{d}{d x} [g (x)] + g (x) \frac{d}{d x} [f (x)]$ where $f (x) = x^{2}$ and $g (x) = y^{- x^{3} + y + 5}$ .

$x^{2} \frac{d}{d x} [y^{- x^{3} + y + 5}] + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 3

Differentiate using the Generalized Power Rule which states that $\frac{d}{d x} [f^{g}]$ is $f^{g} (f' \frac{g}{f} + g' \ln (f))$ where $f = y$ and $g = - x^{3} + y + 5$ .

$x^{2} (\frac{d}{d x} [y] ((- x^{3} + y + 5) y^{- x^{3} + y + 5 - 1}) + \frac{d}{d x} [- x^{3} + y + 5] (y^{- x^{3} + y + 5} \ln (y))) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.1

Subtract $1$ from $5$ .

$x^{2} (\frac{d}{d x} [y] ((- x^{3} + y + 5) y^{- x^{3} + y + 4}) + \frac{d}{d x} [- x^{3} + y + 5] (y^{- x^{3} + y + 5} \ln (y))) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.2

Since $y$ is constant with respect to $x$ , the derivative of $y$ with respect to $x$ is $0$ .

$x^{2} (0 ((- x^{3} + y + 5) y^{- x^{3} + y + 4}) + \frac{d}{d x} [- x^{3} + y + 5] (y^{- x^{3} + y + 5} \ln (y))) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.3.1

Multiply $- x^{3} + y + 5$ by $0$ .

$x^{2} (0 y^{- x^{3} + y + 4} + \frac{d}{d x} [- x^{3} + y + 5] (y^{- x^{3} + y + 5} \ln (y))) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.3.2

Multiply $0$ by $y^{- x^{3} + y + 4}$ .

$x^{2} (0 + \frac{d}{d x} [- x^{3} + y + 5] (y^{- x^{3} + y + 5} \ln (y))) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.3.3

Add $0$ and $\frac{d}{d x} [- x^{3} + y + 5] (y^{- x^{3} + y + 5} \ln (y))$ .

$x^{2} (\frac{d}{d x} [- x^{3} + y + 5] (y^{- x^{3} + y + 5} \ln (y))) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.4

By the Sum Rule, the derivative of $- x^{3} + y + 5$ with respect to $x$ is $\frac{d}{d x} [- x^{3}] + \frac{d}{d x} [y] + \frac{d}{d x} [5]$ .

$x^{2} ((\frac{d}{d x} [- x^{3}] + \frac{d}{d x} [y] + \frac{d}{d x} [5]) (y^{- x^{3} + y + 5} \ln (y))) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.5

Since $- 1$ is constant with respect to $x$ , the derivative of $- x^{3}$ with respect to $x$ is $- \frac{d}{d x} [x^{3}]$ .

$x^{2} ((- \frac{d}{d x} [x^{3}] + \frac{d}{d x} [y] + \frac{d}{d x} [5]) y^{- x^{3} + y + 5} \ln (y)) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.6

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 3$ .

$x^{2} ((- (3 x^{2}) + \frac{d}{d x} [y] + \frac{d}{d x} [5]) y^{- x^{3} + y + 5} \ln (y)) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.7

Multiply $3$ by $- 1$ .

$x^{2} ((- 3 x^{2} + \frac{d}{d x} [y] + \frac{d}{d x} [5]) y^{- x^{3} + y + 5} \ln (y)) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.8

Since $y$ is constant with respect to $x$ , the derivative of $y$ with respect to $x$ is $0$ .

$x^{2} ((- 3 x^{2} + 0 + \frac{d}{d x} [5]) y^{- x^{3} + y + 5} \ln (y)) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.9

Add $- 3 x^{2}$ and $0$ .

$x^{2} ((- 3 x^{2} + \frac{d}{d x} [5]) y^{- x^{3} + y + 5} \ln (y)) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.10

Since $5$ is constant with respect to $x$ , the derivative of $5$ with respect to $x$ is $0$ .

$x^{2} ((- 3 x^{2} + 0) y^{- x^{3} + y + 5} \ln (y)) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 4.11

Add $- 3 x^{2}$ and $0$ .

$x^{2} (- 3 x^{2} y^{- x^{3} + y + 5} \ln (y)) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$

Step 5.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$x^{2 + 2} (- 3 y^{- x^{3} + y + 5} \ln (y)) + y^{- x^{3} + y + 5} \frac{d}{d x} [x^{2}]$
