simplify (5/7)^5×(5/7)^-3×(7/5)^2​

Answer 1

Step-by-step explanation:

$({ \frac{5}{7}) }^{5} \times ({ \frac{5}{7} )}^{ - 3} \times ({ \frac{7}{5} )}^{2}$

$( { \frac{5}{7} )}^{5} \times ({ \frac{5}{7}) }^{ - 3} \times ({ \frac{5}{7}) }^{ - 2}$

$( { \frac{5}{7} )}^{5 - 3 - 2}$

$({ \frac{5}{7} )}^{0}$
