Answer 1

Answer:

$\frac{16}{49}$

Step-by-step explanation:

$(\frac{4}{7} )^{-5} \times (\frac{7}{4} )^{-7}$

= $(\frac{7}{4} )^{5} \times (\frac{4}{7} )^{7}$

= $(\frac{7}{4} )^{5} \times (\frac{4}{7} )^{5} \times (\frac{4}{7} )^{2}$

= $(\frac{7}{4} \times \frac{4}{7} )^{5}\times (\frac{4}{7} )^{2}$

= $(1 )^{5}\times (\frac{16}{49} )$

= $\frac{16}{49}$

Answer 2

Step-by-step explanation:

(4/7) -5 × (7/4)-7

(4/7)-⁵ × (7/4)-⁵ × (7/4)²

(4/7 × 7/4) -⁵ × 49/16

(28/28)-⁵ × 49/16

(1)-⁵ × 49/16

(1)⁵ × 16/49

=16/49
