1 = \frac{1}{1}

= \frac{1}{1} \div \frac{1}{5}

Apply the fraction rule:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{1}{1} \times \frac{5}{1}

Apply rule

\frac{a}{a} = 1

\frac{1}{1} = 1

= 1 \times \frac{5}{1}

Apply rule

\frac{a}{1} = a

= 1 \times 5

1 - e^{- 4}

\frac{x ^{2} + 12 x + 36}{x ^{2} - 36}

524 \cdot 310

\frac{2 x ^{2} - 3 x - 2}{6 x + 3} \cdot \frac{3 x + 6}{x ^{2} - 4}
