Hello, ceasar_19134!

How many integers between 50,000 and 60,000 are perfect squares?

Since √50,000 = 223.505..., the first number is 224² = 50,176

Since √60,000 = 244.948..., the last number is: 244² = 59,536

Hence, they are: .224², 225², 226², . . . 244²

Therefore, there are: .244 - 224 + 1 .= .21 perfect squares.
