Step 6

Combine.

$\frac{8 π^{3} \cdot 1}{q^{6} (3 π^{6} q^{6})}$

Step 7

Multiply $q^{6}$ by $q^{6}$ by adding the exponents.

Move $q^{6}$ .

$\frac{8 π^{3} \cdot 1}{q^{6} q^{6} (3 π^{6})}$

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

$\frac{8 π^{3} \cdot 1}{q^{6 + 6} (3 π^{6})}$

Add $6$ and $6$ .

$\frac{8 π^{3} \cdot 1}{q^{12} (3 π^{6})}$

Step 8

Multiply $8 π^{3}$ by $1$ .

$\frac{8 π^{3}}{q^{12} (3 π^{6})}$

Step 9

Cancel the common factor of $π^{3}$ and $π^{6}$ .

Factor $π^{3}$ out of $8 π^{3}$ .

$\frac{π^{3} \cdot 8}{q^{12} (3 π^{6})}$

Cancel the common factors.

Factor $π^{3}$ out of $q^{12} (3 π^{6})$ .

$\frac{π^{3} \cdot 8}{π^{3} (q^{12} (3 π^{3}))}$
