${(s - 5 v)}^{5}$

Step 1

Use the Binomial Theorem.

$s^{5} + 5 s^{4} (- 5 v) + 10 s^{3} {(- 5 v)}^{2} + 10 s^{2} {(- 5 v)}^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.1

Rewrite using the commutative property of multiplication.

$s^{5} + 5 \cdot - 5 s^{4} v + 10 s^{3} {(- 5 v)}^{2} + 10 s^{2} {(- 5 v)}^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.2

Multiply $5$ by $- 5$ .

$s^{5} - 25 s^{4} v + 10 s^{3} {(- 5 v)}^{2} + 10 s^{2} {(- 5 v)}^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.3

Apply the product rule to $- 5 v$ .

$s^{5} - 25 s^{4} v + 10 s^{3} ({(- 5)}^{2} v^{2}) + 10 s^{2} {(- 5 v)}^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.4

Rewrite using the commutative property of multiplication.

$s^{5} - 25 s^{4} v + 10 \cdot {(- 5)}^{2} s^{3} v^{2} + 10 s^{2} {(- 5 v)}^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.5

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

$s^{5} - 25 s^{4} v + 10 \cdot 25 s^{3} v^{2} + 10 s^{2} {(- 5 v)}^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.6

Multiply $10$ by $25$ .

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} + 10 s^{2} {(- 5 v)}^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.7

Apply the product rule to $- 5 v$ .

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} + 10 s^{2} ({(- 5)}^{3} v^{3}) + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.8

Rewrite using the commutative property of multiplication.

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} + 10 \cdot {(- 5)}^{3} s^{2} v^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.9

Raise $- 5$ to the power of $3$ .

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} + 10 \cdot - 125 s^{2} v^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.10

Multiply $10$ by $- 125$ .

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} - 1250 s^{2} v^{3} + 5 s {(- 5 v)}^{4} + {(- 5 v)}^{5}$

Step 2.11

Apply the product rule to $- 5 v$ .

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} - 1250 s^{2} v^{3} + 5 s ({(- 5)}^{4} v^{4}) + {(- 5 v)}^{5}$

Step 2.12

Rewrite using the commutative property of multiplication.

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} - 1250 s^{2} v^{3} + 5 \cdot {(- 5)}^{4} s v^{4} + {(- 5 v)}^{5}$

Step 2.13

Raise $- 5$ to the power of $4$ .

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} - 1250 s^{2} v^{3} + 5 \cdot 625 s v^{4} + {(- 5 v)}^{5}$

Step 2.14

Multiply $5$ by $625$ .

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} - 1250 s^{2} v^{3} + 3125 s v^{4} + {(- 5 v)}^{5}$

Step 2.15

Apply the product rule to $- 5 v$ .

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} - 1250 s^{2} v^{3} + 3125 s v^{4} + {(- 5)}^{5} v^{5}$

Step 2.16

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

$s^{5} - 25 s^{4} v + 250 s^{3} v^{2} - 1250 s^{2} v^{3} + 3125 s v^{4} - 3125 v^{5}$
