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 ...
A six-digit number, it is a perfect square number, and the last three digits are all 4. Such six-digit numbers have . 相关知识点: 试题来源: 解析 3 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 perfect square can only end in 9 if the last digit of n is either 3 or 7. Therefore, we check: - n=93 (since 90, 91, 92, and 94 do not end in 3 or 7) 5. Calculate n2: Now we calculate: n2=932=8649 6. Identify a and b: From the number 8649, we can see that: ...

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!....
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:...
To find the least number A such that 10A is a perfect square and 35A is a perfect cube, we can follow these steps: Step 1: Prime FactorizationFirst, we need to factor 10 and 35:- 10=21×51- 35=51×71 Step 2: Conditions for Perfect Square and Perfect CubeFor 10A to be a perfec...
