Step 4.1

Multiply $\frac{n^{2} + 5}{4 (n - 1)}$ by $\frac{3 n^{2} + n - 5}{4 (n - 1)}$ .

$\frac{(n^{2} + 5) (3 n^{2} + n - 5)}{4 (n - 1) (4 (n - 1))}$

Step 4.2

Multiply $4$ by $4$ .

$\frac{(n^{2} + 5) (3 n^{2} + n - 5)}{16 (n - 1) (n - 1)}$

Step 4.3

Raise $n - 1$ to the power of $1$ .

$\frac{(n^{2} + 5) (3 n^{2} + n - 5)}{16 ({(n - 1)}^{1} (n - 1))}$

Step 4.4

Raise $n - 1$ to the power of $1$ .

$\frac{(n^{2} + 5) (3 n^{2} + n - 5)}{16 ({(n - 1)}^{1} {(n - 1)}^{1})}$

Step 4.5

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\frac{(n^{2} + 5) (3 n^{2} + n - 5)}{16 {(n - 1)}^{1 + 1}}$

Step 4.6

Add $1$ and $1$ .

$\frac{(n^{2} + 5) (3 n^{2} + n - 5)}{16 {(n - 1)}^{2}}$
