Solution steps

\frac{5 π}{2} - 2 π

Convert element to fraction:

2 π = \frac{2 π 2}{2}

= \frac{5 π}{2} - \frac{2 π 2}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{5 π - 2 π 2}{2}

= \frac{π}{2}

\frac{3}{s ^{2} + 9} + 1

\frac{e ^{- 6} \cdot 6 ^{0}}{0 !}

\frac{ln ( 25 )}{ln ( 5 ^{- 3} )}

\frac{( \frac{3}{8} ) ^{7}}{( \frac{3}{8} ) ^{2}}

\frac{3 + 3}{2}
