No, not always since: if a number is more than 1, then its square root is smaller than the number. if a number is less than 1, then its square root is bigger than the number.
yes every # has a square root, but it is not always easy!
The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i
No. The square root of an integer is always either an integer or an irrational number.
No, it is imaginary, since the square root of a negative number is always imaginary
It is if the number is more than ' 1 '. If the number is less than ' 1 ', then it's smaller than its own square root.
There are two square roots of a perfect square: a positive number and the same number as a negative number. The square root of a perfect square will always be an integer.
Not always as for instance the square root of 16 is 4 which is a rational number but the square root of 2 is an irrational number.
The square root of a negative number cannot be expressed with integers. The square root of a negative number is always imaginary.
