Step 2.1.1

Apply the product rule to $2 a b$ .

${(2 a)}^{3} b^{3} + 3 {(2 a b)}^{2} c + 3 (2 a b) c^{2} + c^{3}$

Step 2.1.2

Apply the product rule to $2 a$ .

$2^{3} a^{3} b^{3} + 3 {(2 a b)}^{2} c + 3 (2 a b) c^{2} + c^{3}$

Step 2.2

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

$8 a^{3} b^{3} + 3 {(2 a b)}^{2} c + 3 (2 a b) c^{2} + c^{3}$

Step 2.3

Step 2.3.1

Apply the product rule to $2 a b$ .

$8 a^{3} b^{3} + 3 ({(2 a)}^{2} b^{2}) c + 3 (2 a b) c^{2} + c^{3}$

Step 2.3.2

Apply the product rule to $2 a$ .

$8 a^{3} b^{3} + 3 (2^{2} a^{2} b^{2}) c + 3 (2 a b) c^{2} + c^{3}$

Step 2.4

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

$8 a^{3} b^{3} + 3 (4 a^{2} b^{2}) c + 3 (2 a b) c^{2} + c^{3}$

Step 2.5
