+174 How many numbers between 50 and 250 (inclusive) are not perfect squares?
+981 The strategy here is see how many numbers there are, and then subtract the total amount of perfect squares.
There are a total of $250 - 50 + 1$, or 201, numbers.
Between 50 and 250, there are perfect squares:
64, 81, 100, 121, 144, 169, 196, and 225.
8 out of the 201 numbers are perfect squares.
So there are 201 - 8 numbers that are not perfect squares.
