tolong kerjakan ya dan di kasih cara yang jelas......terimakasih banyak

NO. 71
[tex] = \sqrt[m]{ \sqrt[n]{ {a}^{p} } } \\ = \sqrt[m]{ {a}^{ \frac{p}{n} } } \\ = {a}^{ \frac{ \frac{p}{n} }{m} } \\ = {a}^{ \frac{p}{n} \times \frac{1}{m} } \\ = {a}^{ \frac{p}{nm} } [/tex]
Jawaban A.

NO. 72
[tex] = {a}^{ \frac{1}{5} } \times {a}^{ \frac{2}{3} } \times {a}^{ \frac{4}{5} } \\ = {a}^{ (\frac{1}{5} + \frac{2}{3} + \frac{4}{5}) } \\ = {a}^{ \frac{3 + 10 + 12}{15} } \\ = {a}^{ \frac{25}{15} } \\ = {a}^{ \frac{5}{3} } [/tex]
