Solution steps

\frac{π}{4} + 2 π

Convert element to fraction:

2 π = \frac{2 π 4}{4}

= \frac{π}{4} + \frac{2 π 4}{4}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{π + 2 π 4}{4}

π + 2 π 4 = 9 π

= \frac{9 π}{4}

∣ a ∣ < 3

\frac{4}{3} \cdot \frac{3}{7}

\frac{x \cdot 2 x}{2} + 17 = \frac{x + 2 + 2 x + 4}{2}

\frac{y ^{- 9} x ^{- 8}}{z ^{- 2}}

∣ 2 x - 12 ∣ \leq 8
