nilai dari 2^-3 + 3^-2 / 2^-3 - 3^-2 adalah...

[tex] {2}^{ - 3} + {3}^{ - 2} \div {2}^{ - 3} - {3}^{ - 2} \\ \frac{1}{ 2^{ 3} } + \frac{1}{ {3}^{2} } \times {2}^{3} - \frac{1}{ {3}^{2} } \\ \frac{1}{8} + \frac{1}{9} \times 9 - \frac{1}{9} \\ \frac{1}{8} + \frac{8}{9} - \frac{1}{9} = \frac{9 + 64 - 8}{72} \\ = \frac{65}{75} [/tex]
Maaf ya klo salah :)
Semoga membantu.
