| ① | Multiply $16$ by $ \dfrac{x^2}{16} $ to get $ x^2$. Step 1: Write $ 16 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Cancel $ \color{blue}{ 16 } $ in first and second fraction. Step 3: Multiply numerators and denominators. Step 4: Simplify numerator and denominator. $$ \begin{aligned} 16 \cdot \frac{x^2}{16} & \xlongequal{\text{Step 1}} \frac{16}{\color{red}{1}} \cdot \frac{x^2}{16} \xlongequal{\text{Step 2}} \frac{\color{blue}{1}}{1} \cdot \frac{x^2}{\color{blue}{1}} = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 1 \cdot x^2 }{ 1 \cdot 1 } \xlongequal{\text{Step 4}} \frac{ x^2 }{ 1 } =x^2 \end{aligned} $$ |
| ② | $$ 1 x^2 x^3 = x^{2 + 3} = x^5 $$ |
