${(n - 4)}^{4}$

Step 1

Use the Binomial Theorem.

$n^{4} + 4 n^{3} \cdot - 4 + 6 n^{2} {(- 4)}^{2} + 4 n {(- 4)}^{3} + {(- 4)}^{4}$

Step 2.1

Multiply $- 4$ by $4$ .

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

Step 2.2

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

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

Step 2.3

Multiply $16$ by $6$ .

$n^{4} - 16 n^{3} + 96 n^{2} + 4 n {(- 4)}^{3} + {(- 4)}^{4}$

Step 2.4

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

$n^{4} - 16 n^{3} + 96 n^{2} + 4 n \cdot - 64 + {(- 4)}^{4}$

Step 2.5

Multiply $- 64$ by $4$ .

$n^{4} - 16 n^{3} + 96 n^{2} - 256 n + {(- 4)}^{4}$

Step 2.6

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

$n^{4} - 16 n^{3} + 96 n^{2} - 256 n + 256$
