Step 5.5.3.5.3.1

Move $x^{4}$ .

$x' = \frac{\sqrt{(1 + 8 x^{5}) (1 - 8 x^{5})} (64 (x^{4} x^{6}) - 1)}{40 x^{4} (1 + 8 x^{5}) (1 - 8 x^{5})}$

Step 5.5.3.5.3.2

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

$x' = \frac{\sqrt{(1 + 8 x^{5}) (1 - 8 x^{5})} (64 x^{4 + 6} - 1)}{40 x^{4} (1 + 8 x^{5}) (1 - 8 x^{5})}$

Step 5.5.3.5.3.3

Add $4$ and $6$ .

$x' = \frac{\sqrt{(1 + 8 x^{5}) (1 - 8 x^{5})} (64 x^{10} - 1)}{40 x^{4} (1 + 8 x^{5}) (1 - 8 x^{5})}$

Step 5.5.3.5.4

Rewrite $64 x^{10}$ as ${(8 x^{5})}^{2}$ .

$x' = \frac{\sqrt{(1 + 8 x^{5}) (1 - 8 x^{5})} ({(8 x^{5})}^{2} - 1)}{40 x^{4} (1 + 8 x^{5}) (1 - 8 x^{5})}$

Step 5.5.3.5.5

Step 5.5.3.5.6

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = 8 x^{5}$ and $b = 1$ .

$x' = \frac{\sqrt{(1 + 8 x^{5}) (1 - 8 x^{5})} (8 x^{5} + 1) (8 x^{5} - 1)}{40 x^{4} (1 + 8 x^{5}) (1 - 8 x^{5})}$
