Step-by-step explanation:

1 Use Division Distributive Property:

5³/7³ ÷ (25/21)³

2 Simplify 5³ to 125

125/7³ ÷ (25/21)³

3 Simplify 7³ to 343

125/343  ÷ (25/21)³

4 Use Division Distributive Property

125/343 ÷ 25 ³ /21 ³

5 Simplify 25 ³  to 15625.

125/343 ÷ 15625/21 ³

6 Simplify 21 ³  to 9261.

125/343 ÷ 15625/9261

7 Use the reciprocal rule of fractions

$\frac{125}{343} * \frac{9261}{15625}$

8 Simplify

$\frac{1157625}{5359375}$

9 further simplified
