Solution steps

\frac{π}{2} + 4 π

Convert element to fraction:

4 π = \frac{4 π 2}{2}

= \frac{π}{2} + \frac{4 π 2}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{π + 4 π 2}{2}

π + 4 π 2 = 9 π

= \frac{9 π}{2}

(- 2) + (- 3)

[\frac{( 3 - \frac{1}{2} ) ( 1 + \frac{1}{4} )}{( 2 - \frac{2}{3} ) ( \frac{1}{2} + \frac{1}{3} )}]^{2}

4 x^{2} + 4 x^{2}

x - \frac{x}{3}
