### Instruction: What is the value of $525^2 - 475^2$?### Response: Let's use the difference of squares formula.
Right, the difference of squares formula is $a^2-b^2=(a+b)(a-b)$.
So, if we plug in the numbers, we get $525^2-475^2=(525+475)(525-475)$.
And if we simplify that, we get $1000*50$ which is $50,000$.
