Answer 1

See below

Explanation:

`9.( {m}^(3) {n}^(5) )^{ (1)/(4) } \\ = m^{(3)/(4)}n^{(5)/(4)}\\ \\ 10. \sqrt[5]{ \sqrt[4]{x} } \\ = \sqrt[5]{ {x}^{ (1)/(4) } } \\ = {( {x}^{ (1)/(4) } )}^{ (1)/(5) } \\ = {x}^{ (1)/(4) * (1)/(5) } \\ = {x}^{ (1)/(20) } \\ \\ \sqrt[5]{ \sqrt[3]{ {a}^(2) } } \\ = \sqrt[5]{ {a}^{ (2)/(3) } } \\ = {( {a}^{ (2)/(3) } )}^{ (1)/(5) } \\ = {a}^{ (2)/(3) * (1)/(5) } \\ = {a}^{ (2)/(15) }`
