Step 2.1

Apply the product rule to $2 y$ .

$2^{4} y^{4} + 4 {(2 y)}^{3} (- 3 z) + 6 {(2 y)}^{2} {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.2

Raise $2$ to the power of $4$ .

$16 y^{4} + 4 {(2 y)}^{3} (- 3 z) + 6 {(2 y)}^{2} {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.3

Rewrite using the commutative property of multiplication.

$16 y^{4} + 4 \cdot - 3 {(2 y)}^{3} z + 6 {(2 y)}^{2} {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.4

Multiply $4$ by $- 3$ .

$16 y^{4} - 12 {(2 y)}^{3} z + 6 {(2 y)}^{2} {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.5

Apply the product rule to $2 y$ .

$16 y^{4} - 12 (2^{3} y^{3}) z + 6 {(2 y)}^{2} {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.6

Raise $2$ to the power of $3$ .

$16 y^{4} - 12 (8 y^{3}) z + 6 {(2 y)}^{2} {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.7

Multiply $8$ by $- 12$ .

$16 y^{4} - 96 y^{3} z + 6 {(2 y)}^{2} {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.8

Apply the product rule to $2 y$ .

$16 y^{4} - 96 y^{3} z + 6 (2^{2} y^{2}) {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.9

Raise $2$ to the power of $2$ .

$16 y^{4} - 96 y^{3} z + 6 (4 y^{2}) {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.10

Multiply $4$ by $6$ .

$16 y^{4} - 96 y^{3} z + 24 y^{2} {(- 3 z)}^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.11

Apply the product rule to $- 3 z$ .

$16 y^{4} - 96 y^{3} z + 24 y^{2} ({(- 3)}^{2} z^{2}) + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.12

Rewrite using the commutative property of multiplication.

$16 y^{4} - 96 y^{3} z + 24 \cdot {(- 3)}^{2} y^{2} z^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.13

Raise $- 3$ to the power of $2$ .

$16 y^{4} - 96 y^{3} z + 24 \cdot 9 y^{2} z^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.14

Multiply $24$ by $9$ .

$16 y^{4} - 96 y^{3} z + 216 y^{2} z^{2} + 4 (2 y) {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.15

Multiply $2$ by $4$ .

$16 y^{4} - 96 y^{3} z + 216 y^{2} z^{2} + 8 y {(- 3 z)}^{3} + {(- 3 z)}^{4}$

Step 2.16

Apply the product rule to $- 3 z$ .

$16 y^{4} - 96 y^{3} z + 216 y^{2} z^{2} + 8 y ({(- 3)}^{3} z^{3}) + {(- 3 z)}^{4}$

Step 2.17

Rewrite using the commutative property of multiplication.

$16 y^{4} - 96 y^{3} z + 216 y^{2} z^{2} + 8 \cdot {(- 3)}^{3} y z^{3} + {(- 3 z)}^{4}$

Step 2.18

Raise $- 3$ to the power of $3$ .

$16 y^{4} - 96 y^{3} z + 216 y^{2} z^{2} + 8 \cdot - 27 y z^{3} + {(- 3 z)}^{4}$

Step 2.19

Multiply $8$ by $- 27$ .

$16 y^{4} - 96 y^{3} z + 216 y^{2} z^{2} - 216 y z^{3} + {(- 3 z)}^{4}$

Step 2.20

Apply the product rule to $- 3 z$ .

$16 y^{4} - 96 y^{3} z + 216 y^{2} z^{2} - 216 y z^{3} + {(- 3)}^{4} z^{4}$

Step 2.21

Raise $- 3$ to the power of $4$ .

$16 y^{4} - 96 y^{3} z + 216 y^{2} z^{2} - 216 y z^{3} + 81 z^{4}$
