$<b>$
(ii)
$\frac{ {x}^{ \frac{6}{5} } }{ {x}^{ \frac{1}{5} } } \\ \\ as \: we \: know \\ {x}^{m} \div {x}^{n} = {x}^{(m - n)} \\ \\ {x}^{ (\frac{6}{5} - \frac{1}{5} ) } \\ = {x}^{ \frac{5}{5} } \\ = {x}^{1} \\ \\ = x$
(v)

$x {}^{ \frac{ - 7}{2} } \times 2x {}^{ \frac{ - 1}{2} } \\ = 2 \times x {}^{ \frac{ - 7}{2} - \frac{1}{2} } \\ = 2 \times x {}^{ \frac{ - 8}{2} } \\ = 2x {}^{ - 4}$
