Slide 8 - Quiz

\frac{​ ( \frac{​ 3 ​ ​}{​ x ​} ) ​ ​}{​ 7 ​} = \frac{​ 3 ​ ​}{​ x ​} \cdot \frac{​ 1 ​ ​}{​ 7 ​} = \frac{​ 3 ​ ​}{​ 7 x ​}

Slide 9 - Slide

\frac{​ x ​ ​}{​ 1 6 ​}

(4 x)

\frac{​ x ​ ​}{​ 1 6 ​} \cdot \frac{​ 4 x ​ ​}{​ 1 ​} = \frac{​ 4 x ^{​ 2 ​ ​} ​ ​}{​ 1 6 ​} = \frac{​ 1 ​ ​}{​ 4 ​} x^{​ 2 ​ ​}

\frac{​ x ​ ​}{​ 1 6 ​} \cdot \frac{​ 1 ​ ​}{​ 4 x ​} = \frac{​ x ​ ​}{​ 6 4 x ​} = \frac{​ 1 ​ ​}{​ 6 4 ​}

\frac{​ 1 6 ​ ​}{​ x ​} \cdot \frac{​ 1 ​ ​}{​ 4 x ​} = \frac{​ 1 6 ​ ​}{​ 4 x ^{​ 2 ​ ​} ​} = \frac{​ 4 ​ ​}{​ x ^{​ 2 ​ ​} ​}

\frac{​ 1 6 ​ ​}{​ x ​} \cdot \frac{​ 4 x ​ ​}{​ 1 ​} = \frac{​ 6 4 x ​ ​}{​ x ​} = 64
