tolong bamtu jawab pakai cara ya terima kasih..

Nomor 7 (Jawaban B)

[tex] = {27}^{ \frac{2}{3} } + {32}^{ \frac{3}{5} } \\ = ( {3}^{3} ) ^{ \frac{2}{3} } + ( {2}^{5} )^{ \frac{3}{5} } \\ = {3}^{2} + {2}^{3} \\ = 9 + 8 \\ = 17[/tex]

Nomor 6 (Jawaban D)

[tex] = {3}^{ - 2} - {2}^{ - 3} \\ = \frac{1}{9} - \frac{1}{8} \\ = \frac{8 - 9}{72} \\ = - \frac{1}{72} [/tex]
