join

- \frac{π}{4} - 2 π

- \frac{9 π}{4}

Decimal Notation

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}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{9 π}{4}

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

(x^{10} - 5 y^{2})^{2}

\frac{( 2 x - 4 )}{3 x} - \frac{( x - 2 )}{3 x}

\frac{0}{cos ( x )}

2. 1^{3}
