Jawaban:

[tex] - \frac{72}{511} \\ [/tex]

Penjelasan dengan langkah-langkah:

a = 3

b = 2

c = 4

[tex] \frac{ {a}^{2} }{ {b}^{ - 3} - {c}^{3} } \\ [/tex]

[tex] = \frac{ {3}^{2} }{ {2}^{ - 3} - {4}^{3} } \\ [/tex]

[tex] = \frac{ {3}^{2} }{ {2}^{ - 3} - {( {2}^{2}) }^{3} } \\ [/tex]

[tex] = \frac{ {3}^{2} }{ {2}^{ - 3} - {2}^{6} } \\ [/tex]

[tex] = \frac{9}{ \frac{1}{ {2}^{3} } - {2}^{6} } \\ [/tex]

[tex] = \frac{9}{ \frac{1}{8} - 64 } \\ [/tex]

[tex] = \frac{9}{ \frac{1 - 512}{8} } \\ [/tex]

[tex] = \frac{9}{ - \frac{511}{8} } \\ [/tex]

[tex] = \frac{9 \times 8}{ - 511} \\ [/tex]

[tex] = - \frac{72}{511} \\ [/tex]
