Step 1.2.1

Raise $y$ to the power of $1$ .

$5 \cdot (y^{1} y^{3} (5 \cdot (- 1)))$

Step 1.2.2

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

$5 \cdot (y^{1 + 3} (5 \cdot (- 1)))$

Step 1.3

Add $1$ and $3$ .

$5 \cdot (y^{4} (5 \cdot (- 1)))$

Step 2

Multiply $5$ by $- 1$ .

$5 \cdot (y^{4} \cdot - 5)$

Step 3

Move $- 5$ to the left of $y^{4}$ .

$5 \cdot (- 5 \cdot y^{4})$

Step 4

Multiply $- 5$ by $5$ .

$- 25 y^{4}$
