how many non perfect square are there between 79 square and 80 square
Answers
The answer is 159.
Explanation: 79×79=6241
80×80=6400
So the number of non perfect
squares is
6400-6241=159
159.
Perfect squares are integers that may be written as the product of an integer by itself or as the second exponent of an integer, or they can be generated by squaring a whole number or an integer.
25 is a perfect square because it is the product of the integer 5 multiplied by itself, 5 5 = 25. However, because it cannot be written as the product of two identical integers, 21 is not a perfect square number.
79² and 80² are both perfect squares of two consecutive whole numbers.
∴ All the numbers lying between the squares of these two numbers will be non perfect squares.
∴ 80² - 79² = 6400 - 6241
∴ 80² - 79² = 159.
∴ There exist 159 non perfect squares between 79² and 80².
