| ① | Multiply $36$ by $ \dfrac{x^8}{6} $ to get $ \dfrac{ 36x^8 }{ 6 } $. Step 1: Write $ 36 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 36 \cdot \frac{x^8}{6} & \xlongequal{\text{Step 1}} \frac{36}{\color{red}{1}} \cdot \frac{x^8}{6} \xlongequal{\text{Step 2}} \frac{ 36 \cdot x^8 }{ 1 \cdot 6 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 36x^8 }{ 6 } \end{aligned} $$ |
| ② | Multiply $ \dfrac{36x^8}{6} $ by $ x^2 $ to get $ \dfrac{ 36x^{10} }{ 6 } $. Step 1: Write $ x^2 $ as a fraction by putting $ \color{red}{ 1 } $ in the denominator. Step 2: Multiply numerators and denominators.
