Step 1.1

Multiply $\frac{1 + \frac{a}{{(1 + a^{2})}^{\frac{1}{2}}}}{a + {(1 + a^{2})}^{\frac{1}{2}}}$ by $\frac{{(1 + a^{2})}^{\frac{1}{2}}}{{(1 + a^{2})}^{\frac{1}{2}}}$ .

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

Step 1.2

Combine.

$\frac{{(1 + a^{2})}^{\frac{1}{2}} (1 + \frac{a}{{(1 + a^{2})}^{\frac{1}{2}}})}{{(1 + a^{2})}^{\frac{1}{2}} (a + {(1 + a^{2})}^{\frac{1}{2}})}$

Step 2

Apply the distributive property.

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

Step 4.1.1

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

$\frac{{(1 + a^{2})}^{\frac{1}{2}} + a}{{(1 + a^{2})}^{\frac{1}{2}} a + {(1 + a^{2})}^{\frac{1}{2} + \frac{1}{2}}}$

Step 4.1.2

Combine the numerators over the common denominator.

$\frac{{(1 + a^{2})}^{\frac{1}{2}} + a}{{(1 + a^{2})}^{\frac{1}{2}} a + {(1 + a^{2})}^{\frac{1 + 1}{2}}}$

Step 4.1.3

Add $1$ and $1$ .

$\frac{{(1 + a^{2})}^{\frac{1}{2}} + a}{{(1 + a^{2})}^{\frac{1}{2}} a + {(1 + a^{2})}^{\frac{2}{2}}}$

Step 4.1.4

Divide $2$ by $2$ .

$\frac{{(1 + a^{2})}^{\frac{1}{2}} + a}{{(1 + a^{2})}^{\frac{1}{2}} a + {(1 + a^{2})}^{1}}$

Step 4.2

Simplify ${(1 + a^{2})}^{1}$ .

$\frac{{(1 + a^{2})}^{\frac{1}{2}} + a}{{(1 + a^{2})}^{\frac{1}{2}} a + 1 + a^{2}}$

Step 4.3

Reorder terms.

$\frac{{(1 + a^{2})}^{\frac{1}{2}} + a}{a^{2} + a {(1 + a^{2})}^{\frac{1}{2}} + 1}$
