Question

Evaluate (4/3)-³ and (-2/3)-⁴​

Answer 1

Answer:

$\frac{ {4}^{ - 3} }{ {3}^{ - 3} } = \frac{ \frac{1}{ {4}^{3} } }{ \frac{1}{ {3}^{3} } } = \frac{ {3}^{3} }{ {4}^{3} } = \frac{27}{64}$

$\frac{ { - 2}^{ - 4} }{ {3}^{ - 4} } = \frac{ \frac{1}{ { - 2}^{4} } }{ \frac{1}{ {3}^{4} } } = \frac{ {3}^{4} }{ { - 2}^{4} } = \frac{81}{16}$
