Answer:
[tex]2.) Answer : \: i \: € \: R \\ Answer : \: i = - 1 \\ 8.) Answer : \: \sqrt[mn]{a} [/tex]
Explanation :
[tex]2.) \: i = \sqrt{ - 1} \\ i = i \\ i \: € \: R \\ Answer : i \: € \: R \\ \\ i \: = \sqrt{ - 1} {}^{6} \\ i = i \: {}^{6} \\ i - i \: {}^{6} = 0\\ i \: ( - 1 \: \times - 1 \: \times - 1 \: \times - 1 \: \times - 1 \: \times - 1) \\ i = - 1 \\ Answer : \: i = - 1 \\ [/tex]
[tex]8.) \: \sqrt[m]{ \sqrt[n]{a} } \\ \sqrt[m + n]{a} \\ \sqrt[mn]{a} \\ Answer : \: \sqrt[m + n]{a} \\ \\ [/tex]
