Step 2.1

Factor $b$ out of $b^{2}$ .

$\frac{b \cdot b + 7 b}{8} \cdot \frac{b}{b + 7}$

Step 2.2

Factor $b$ out of $7 b$ .

$\frac{b \cdot b + b \cdot 7}{8} \cdot \frac{b}{b + 7}$

Step 2.3

Factor $b$ out of $b \cdot b + b \cdot 7$ .

Step 3.1

Factor $b + 7$ out of $b (b + 7)$ .

$\frac{(b + 7) b}{8} \cdot \frac{b}{b + 7}$

Step 3.2

Cancel the common factor.

$\frac{(b + 7) b}{8} \cdot \frac{b}{b + 7}$

Step 3.3

Rewrite the expression.

$\frac{b}{8} b$

Step 4

Combine $\frac{b}{8}$ and $b$ .

$\frac{b \cdot b}{8}$

Step 5

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

$\frac{b^{1} b}{8}$

Step 6

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

$\frac{b^{1} b^{1}}{8}$

Step 7

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

$\frac{b^{1 + 1}}{8}$

Step 8

Add $1$ and $1$ .

$\frac{b^{2}}{8}$
