Yes.
Yes because the square root of 16 is 4
The square root of 18, rounded to the nearest integer, is 4.
Yes, and it is 4
The square root of -1 is the imaginary number i.So the square root of -4 = 2i
The square root of 4 is 2 (and -2) and is an integer.
Yes, because the square root of 16 is 4 and as a whole number it is an integer
Yes.
Yes because the square root of 16 is 4
The root of a perfect square will be an integer, but will be both the positive and negative values. For instance, the square root of 4 is plus or minus 2 (±2), as both integral answers are valid. The positive real root is the answer that many books give. It is sometimes called the primary root. But the key point is both roots are valid.
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.
The square root of 18, rounded to the nearest integer, is 4.
Yes, and it is 4
It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).
