What is the smallest positive integer n such that the rightmost three digits of n^2 and (n+2)^2 are the same?
Hey there, Guest!
So, let's solve your problem:
Step 1: Simplify both sides of the equation.
Step 2: Subtract n^2 from both sides.
Step 3: Flip the equation.
Step 4: Subtract 4 from both sides.
Step 5: Divide both sides by 4.
Hope this helped! :)
