perfect squares
Only if the integer is a perfect square.
The square root of every perfect square is an integer. However, there are also square roots of numbers that are not perfect squares.
Of course they can. Every integer greater than zero is a square root.
The square roots of 100 are +10 and -10 . They're both integers.
120 is not the square of an integer, its square roots, rounded to two decimal places, are ±10.95.
No. The only square roots of integers that are rational numbers only when the integer is a perfect square.
There are two distinct roots of any positive integer, the absolute value and its negative equivalent. Therefore, the square roots of 150, rounded to two decimal places, are ±12.25.
The square roots of 9 are +3 and -3. The integers of their negatives are -3 and +3 respectively.
no.No. The square root of 5 is an irrational number. The two closest numbers with integer square roots are 4 (with a square root of 2) and 9 (with a square root of 3). Since there are no integers between 2 and 3 and 5 lies between 4 and 9, it's pretty evident that it can't have an integer square root.
Yes and no. It depends on your definition of square root. By the actual one, yes. All non-negative numbers have a square root. That square root might be irrational but it has a square root, nonetheless. 10 isn't a square number because there's no integer that can be squared to make ten but 10 definitely has a square root: 3.16227766....... If by square root you mean an integer square root, then no. If a number has an integer as its square root then you could square that integer to get the number, making it a square number.
