$y = {(5 x^{3} - 3)}^{5} \sqrt[4]{- 4 x^{5} - 3}$

Step 1

Step 23.2.5.1

Factor $5$ out of $- 325 x^{5}$ .

$\frac{{(5 x^{3} - 3)}^{4} x^{2} (5 (- 65 x^{5}) + 15 x^{2} - 225)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.2.5.2

Factor $5$ out of $15 x^{2}$ .

$\frac{{(5 x^{3} - 3)}^{4} x^{2} (5 (- 65 x^{5}) + 5 (3 x^{2}) - 225)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.2.5.3

Factor $5$ out of $- 225$ .

$\frac{{(5 x^{3} - 3)}^{4} x^{2} (5 (- 65 x^{5}) + 5 (3 x^{2}) + 5 (- 45))}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.2.5.4

Factor $5$ out of $5 (- 65 x^{5}) + 5 (3 x^{2})$ .

$\frac{{(5 x^{3} - 3)}^{4} x^{2} (5 (- 65 x^{5} + 3 x^{2}) + 5 (- 45))}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.2.5.5

Factor $5$ out of $5 (- 65 x^{5} + 3 x^{2}) + 5 (- 45)$ .

$\frac{{(5 x^{3} - 3)}^{4} x^{2} (5 (- 65 x^{5} + 3 x^{2} - 45))}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

$\frac{{(5 x^{3} - 3)}^{4} x^{2} \cdot 5 (- 65 x^{5} + 3 x^{2} - 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.3

Move $5$ to the left of ${(5 x^{3} - 3)}^{4} x^{2}$ .

$\frac{5 {(5 x^{3} - 3)}^{4} x^{2} (- 65 x^{5} + 3 x^{2} - 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.4

Reorder terms.

$\frac{5 x^{2} {(5 x^{3} - 3)}^{4} (- 65 x^{5} + 3 x^{2} - 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.5

Factor $- 1$ out of $- 65 x^{5}$ .

$\frac{5 x^{2} {(5 x^{3} - 3)}^{4} (- (65 x^{5}) + 3 x^{2} - 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.6

Factor $- 1$ out of $3 x^{2}$ .

$\frac{5 x^{2} {(5 x^{3} - 3)}^{4} (- (65 x^{5}) - (- 3 x^{2}) - 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.7

Factor $- 1$ out of $- (65 x^{5}) - (- 3 x^{2})$ .

$\frac{5 x^{2} {(5 x^{3} - 3)}^{4} (- (65 x^{5} - 3 x^{2}) - 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.8

Rewrite $- 45$ as $- 1 (45)$ .

$\frac{5 x^{2} {(5 x^{3} - 3)}^{4} (- (65 x^{5} - 3 x^{2}) - 1 (45))}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.9

Factor $- 1$ out of $- (65 x^{5} - 3 x^{2}) - 1 (45)$ .

$\frac{5 x^{2} {(5 x^{3} - 3)}^{4} (- (65 x^{5} - 3 x^{2} + 45))}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.10

Rewrite $- (65 x^{5} - 3 x^{2} + 45)$ as $- 1 (65 x^{5} - 3 x^{2} + 45)$ .

$\frac{5 x^{2} {(5 x^{3} - 3)}^{4} (- 1 (65 x^{5} - 3 x^{2} + 45))}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.11

Move the negative in front of the fraction.

$- \frac{(5 x^{2} {(5 x^{3} - 3)}^{4}) (65 x^{5} - 3 x^{2} + 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$

Step 23.12

Reorder factors in $- \frac{(5 x^{2} {(5 x^{3} - 3)}^{4}) (65 x^{5} - 3 x^{2} + 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$ .

$- \frac{5 x^{2} {(5 x^{3} - 3)}^{4} (65 x^{5} - 3 x^{2} + 45)}{{(- 4 x^{5} - 3)}^{\frac{3}{4}}}$
