A perfect square is a number that can be expressed as theproduct of two equal integers. Examplesof perfect squares 9 9 is a perfect square because it can be expressed as 3 * 3 (the product of two equal integers). 16 16 is a perfect square because it can be expressed as 4 * 4 (t...
A perfect square is a whole number whose square root is also a whole number. For example, 144 is a perfect square since its square root is 12. How many perfect squares are there between 2 and 20? A: OB: 1 C: 2 D: 3 E: 4 相关知识点: 试题来源: 解析 D略 反馈 收藏 ...
Input:The program asks the user to input a number, which will be checked to see if it’s a perfect square. Square Root Calculation:The Math.sqrt() method is used to calculate the square root of the given number. The square root value is stored in a variable called squareRoot. Integer ...
Because the last three digits are all 4 and the smallest number of perfect square number is 382=1444, the last three digits of such a six-digit difference from 1444 are 0. Assuming k2 is the six-digit number that satisfies the condition, so, k2−382=1000m(m is a natural number), ...

Which of the numbers is a perfect square? (Aperfect square is a whole number that is the product of a whole number with itself. For example, some perfect squares are the bolded ones in the following sequence: 1=1×1.4=2×2, 9=3×3, ..., etc.)A:...
{ return false; } // Iterate from 0 to half of the input number plus 1 for (int i = 0; i <= n / 2 + 1; i++) { // Check if the square of the current iteration is equal to the input number if ((long) i * i == n) { return true; } } // If no perfect square ...

Therefore m!·n! is a perfect square if and only if (m+1)·(m+2)… n. is a perfect square. For the five answer choices, that quantity is 121, 121⋅ 122, 120, 120⋅ 121, and 122, and of those only 121 is a perfect square. Therefore the answer is120!·121!....
