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

Step 1

Apply the product rule to $a b$ .

$\frac{a - b}{\sqrt{a - \sqrt{b}}} - \frac{a + a^{\frac{1}{2}} b^{\frac{1}{2}}}{\sqrt{a + \sqrt{b}}}$

Step 2

Factor $a^{\frac{1}{2}}$ out of $a + a^{\frac{1}{2}} b^{\frac{1}{2}}$ .

Step 2.1

Raise $a$ to the power of $1$ .

$\frac{a - b}{\sqrt{a - \sqrt{b}}} - \frac{a^{1} + a^{\frac{1}{2}} b^{\frac{1}{2}}}{\sqrt{a + \sqrt{b}}}$

Step 2.2

Factor $a^{\frac{1}{2}}$ out of $a^{1}$ .

$\frac{a - b}{\sqrt{a - \sqrt{b}}} - \frac{a^{\frac{1}{2}} a^{\frac{1}{2}} + a^{\frac{1}{2}} b^{\frac{1}{2}}}{\sqrt{a + \sqrt{b}}}$

Step 2.3

Factor $a^{\frac{1}{2}}$ out of $a^{\frac{1}{2}} b^{\frac{1}{2}}$ .

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

Step 2.4

Factor $a^{\frac{1}{2}}$ out of $a^{\frac{1}{2}} a^{\frac{1}{2}} + a^{\frac{1}{2}} (b^{\frac{1}{2}})$ .

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