Evaluate (101•5)(101•5)-(100•5)(100•5)?

To evaluate this expression, we can simplify it step by step.

First, let's simplify the expression inside the parentheses:
(101•5)(101•5) = 101^2 • 5^2 = 10201 • 25

Next, let's simplify the expression outside the parentheses:
(100•5)(100•5) = 100^2 • 5^2 = 10000 • 25

Now, let's subtract the two simplified expressions:
10201 • 25 - 10000 • 25 = (10201 - 10000) • 25 = 201 • 25

Finally, let's calculate the final result:
201 • 25 = 5025

Therefore, (101•5)(101•5)-(100•5)(100•5) = 5025.
