Step 2.1

Apply the product rule to $2 y$ .

$2^{5} y^{5} + 5 {(2 y)}^{4} \cdot 1 + 10 {(2 y)}^{3} \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.2

Raise $2$ to the power of $5$ .

$32 y^{5} + 5 {(2 y)}^{4} \cdot 1 + 10 {(2 y)}^{3} \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.3

Apply the product rule to $2 y$ .

$32 y^{5} + 5 (2^{4} y^{4}) \cdot 1 + 10 {(2 y)}^{3} \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.4

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

$32 y^{5} + 5 (16 y^{4}) \cdot 1 + 10 {(2 y)}^{3} \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.5

Multiply $16$ by $5$ .

$32 y^{5} + 80 y^{4} \cdot 1 + 10 {(2 y)}^{3} \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.6

Multiply $80$ by $1$ .

$32 y^{5} + 80 y^{4} + 10 {(2 y)}^{3} \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.7

Apply the product rule to $2 y$ .

$32 y^{5} + 80 y^{4} + 10 (2^{3} y^{3}) \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.8

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

$32 y^{5} + 80 y^{4} + 10 (8 y^{3}) \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.9

Multiply $8$ by $10$ .

$32 y^{5} + 80 y^{4} + 80 y^{3} \cdot 1^{2} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.10

One to any power is one.

$32 y^{5} + 80 y^{4} + 80 y^{3} \cdot 1 + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.11

Multiply $80$ by $1$ .

$32 y^{5} + 80 y^{4} + 80 y^{3} + 10 {(2 y)}^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.12

Apply the product rule to $2 y$ .

$32 y^{5} + 80 y^{4} + 80 y^{3} + 10 (2^{2} y^{2}) \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.13

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

$32 y^{5} + 80 y^{4} + 80 y^{3} + 10 (4 y^{2}) \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.14

Multiply $4$ by $10$ .

$32 y^{5} + 80 y^{4} + 80 y^{3} + 40 y^{2} \cdot 1^{3} + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.15

One to any power is one.

$32 y^{5} + 80 y^{4} + 80 y^{3} + 40 y^{2} \cdot 1 + 5 (2 y) \cdot 1^{4} + 1^{5}$

Step 2.16
