Explanation:
Given expression can be written as below:
![((7* 3* 2)/(7* 5))^2* (7^0)/(5^(-3))* 5^(-9)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ef0idsf3qyjoz8awjm288tg9xxddczkzg1.png)
To find the value of given expression:
![((7* 3* 2)/(7* 5))^2* (7^0)/(5^(-3))* 5^(-9)=((6)/(5))^2* ((1)/(5^(-3)))^3* (1)/(5^9)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/uzuynwt0a0gmjww4ywku8xv5hge2jt8m46.png)
![=((6)/(5))^2* (5^3)^3* (1)/(5^9)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/fxjztadtwvcrcbt077kqcus3f3gtrl2c8p.png)
![=(36)/(25)* 5^9* (1)/(5^9)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/b48xs73orhf7e5gmab1bpbdgpmqvpcekt9.png)
![=(36)/(25)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/c8x8hlytb5er1fpijt49vfpj8xyel5hnp7.png)
Therefore
![((7* 3* 2)/(7* 5))^2* (7^0)/(5^(-3))* 5^(-9)=(36)/(25)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/lng390m8dtt5xenp5ue36ovuj8mbgrr1yb.png)
