\frac{12}{4 n + 36} : \frac{3}{n + 9}

= \frac{7}{n + 9} + \frac{3}{n + 9}

Apply the fraction rule:

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

= \frac{7 + 3}{n + 9}

Add the numbers:

7 + 3 = 10

= \frac{10}{n + 9}

\frac{- 8 a ^{8} b ^{- 2}}{10 a ^{- 4} b ^{- 10}}

- 2 x^{2} + 12 x - 11 = 0

p^{2} + 9 p - 36

\frac{3 r}{5} - 1 > \frac{2}{5}

(- 4 x)^{- 3}
