See Below.

Step-by-step explanation:

We have the expression:

And we want to prove that it is divisible by 7.

To do so, we can factor out a 5³ from the expression. This yields:

Simplify the parentheses:

We can see that the resulting expression is a value being multiplied by 21.

Since 21 is divisible by 7, our original expression must also be divisible by 7.

Hence proven.
