(v) \(\frac{n  -  3}{5n} + \frac{n^{2}  -  9}{10n^{2}}  -  \frac{8  -  n^{3}}{15n^{3}}\)

(vi) \(\frac{2}{pq} - \frac{3q^{2}  -  p^{2}}{pq^{3}} + \frac{pq  +  q^{2}}{p^{2}q^{2}}\)

2. Reduce the following expressions to its simplest form:

(i) \(\frac{x^{2}  -  4a^{2}}{ax  +  2a^{2}} \times \frac{2a}{x  -  2a}\)

(vi) \(\frac{a^{2}  -  25}{9a^{2}  -  16b^{2}} \times \frac{3a  -  4b}{a^{2}  -  5a}\)

3. Simplify algebraic fractions to its lowest terms:

(i) \(\frac{1  +  z  +  z^{2}}{1  -  z^{3}} + \frac{z  -  z^{2}}{(1  -  z)^{3}}\)

(ii) \(\frac{2m  -  7}{(m  -  3)^{2}} - \frac{2(m  +  2)}{m^{2}  -  9}\)

(iii) \(\frac{2u  -  3v}{uv} + \frac{3u  -  2k}{ku} + \frac{5}{u}\)

(iv) \(\frac{1}{2k^{2} - \frac{1}{2}} + \frac{1}{(2k  +  1)^{2}}\)

(v) \(\frac{1}{(6u  -  2)} - \frac{1}{2(u  -  \frac{1}{3})} - \frac{1}{1  -  3u}\)
