Therefore there are only5perfect squares less than 100 equal to the sum of two consecutive whole numbers. 两个连续整数的总和是多少个数的平方且小于或等于100? 两个连续的整数必须由一个奇数和一个偶数组成.因此,两个连续整数之和始终是奇数.由于偶数整数的平方始终为偶数,奇数整数的平方始终为奇数,因此请...
In order to solve this equation, we first need to figure out what number goes into the blank to make the left side of the equation a perfect square. (This missing number is called the constant.) By doing that, we’ll be able to factor the equation like normal. Step 2: Use the Comp...

To show that √ n is an irrational number unless n is a perfect square, explain how the assumption that √ n is rational leads to a contradiction of the fundamental theorem of arithmetic by the following steps:Explain why the prime number p appears an odd number of times as a factor in...
The formula to find the square root is: y = √a Since, y.y = y2= a; where ‘a’ is the square of a number ‘y’. Properties of Square root Some of the important properties of the square root are as follows: If a number is a perfect square number, then there exists a perfect...
