tolong dijawab ya.....

[tex]8 ^{ \frac{2}{3} } - 27 ^{ - \frac{2}{3} } \\ = \sqrt[3]{8 ^{2} } - \sqrt[3]{27 ^{ - 2} } \\ = \sqrt[3]{(2 ^{3}) ^{2} } - \sqrt[3]{(3 ^{3} ) ^{ - 2} } \\ = 2 ^{2} - 3 ^{ - 2} \\ = 4 - ( \frac{1}{3} )^{2} \\ = 4 - \frac{1}{9} \\ = \frac{36 - 1}{9} \\ = \frac{35}{9} \\ = 3 \frac{8}{9} [/tex]

Jawaban : A. 3 8/9

Maaf Kalau Salah
