Step 2.1

Combine $\frac{{(x + 2)}^{2}}{{(x - 2)}^{\frac{1}{2}}}$ and $2$ .

$\frac{{(x + 2)}^{2} \cdot 2}{{(x - 2)}^{\frac{1}{2}}} {(x + 2)}^{\frac{1}{2}}$

Step 2.2

Combine $\frac{{(x + 2)}^{2} \cdot 2}{{(x - 2)}^{\frac{1}{2}}}$ and ${(x + 2)}^{\frac{1}{2}}$ .

$\frac{{(x + 2)}^{2} \cdot 2 {(x + 2)}^{\frac{1}{2}}}{{(x - 2)}^{\frac{1}{2}}}$

Step 2.3

Multiply ${(x + 2)}^{2}$ by ${(x + 2)}^{\frac{1}{2}}$ by adding the exponents.

Step 2.3.1

Move ${(x + 2)}^{\frac{1}{2}}$ .

$\frac{{(x + 2)}^{\frac{1}{2}} {(x + 2)}^{2} \cdot 2}{{(x - 2)}^{\frac{1}{2}}}$

Step 2.3.2

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

$\frac{{(x + 2)}^{\frac{1}{2} + 2} \cdot 2}{{(x - 2)}^{\frac{1}{2}}}$

Step 2.3.3

To write $2$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$\frac{{(x + 2)}^{\frac{1}{2} + 2 \cdot \frac{2}{2}} \cdot 2}{{(x - 2)}^{\frac{1}{2}}}$

Step 2.3.4

Combine $2$ and $\frac{2}{2}$ .

$\frac{{(x + 2)}^{\frac{1}{2} + \frac{2 \cdot 2}{2}} \cdot 2}{{(x - 2)}^{\frac{1}{2}}}$

Step 2.3.5

Combine the numerators over the common denominator.

$\frac{{(x + 2)}^{\frac{1 + 2 \cdot 2}{2}} \cdot 2}{{(x - 2)}^{\frac{1}{2}}}$

Step 2.3.6

Simplify the numerator.

Step 2.3.6.1

Multiply $2$ by $2$ .

$\frac{{(x + 2)}^{\frac{1 + 4}{2}} \cdot 2}{{(x - 2)}^{\frac{1}{2}}}$

Step 2.3.6.2

Add $1$ and $4$ .

$\frac{{(x + 2)}^{\frac{5}{2}} \cdot 2}{{(x - 2)}^{\frac{1}{2}}}$

Step 3

Move $2$ to the left of ${(x + 2)}^{\frac{5}{2}}$ .

$\frac{2 {(x + 2)}^{\frac{5}{2}}}{{(x - 2)}^{\frac{1}{2}}}$
