If the date is March 1, 2007, in how many whole years will the number representing the year be the smallest perfect square greater than 2007?

I'm not sure if you are going to like how I solved the problem, but I solved it anyways.

 

We already know that \(40^2\) is 1600 and that \(50^2\) is 2500, that means the answer is between 40 and 50. Seeing that 2000 (2007 rounds to 2000) is closer to 1600, we try if \(44^2\) will fit the answer. \(44^2\) apparently is 1936, so the next possible solution is 45. Seeing that \(45^2\)is 2025, we can know that \(\boxed{18} \) years after 2007 will be the answer

 

If somebody finds a better way to solve this, please post it.

Take the square root of 2007 =~44.8 - round it up to the next whole number, or 45.

45^2 = 2025 - 2007 = 18 - years.
