Sometimes the square root of a positive number can be irrational, as in the square root of 2 (which is a non-perfect square number), but sometimes it is a rational number, as in the square root of 25 (which is a perfect square number).
Yes, as is the positive square root.
The square root of 361 is 19.
√-72 = i√(622) = i6√2
The two square roots of any positive number are the positive square root and the negative square root. The positive square root of 49 is 7, because 72=49, while the negative square root is -7, because -72=49.

Well, there technically is not a way to simplify the square root of 2, but the simplified version of the square root of 72 is 6 square root 2
36
6 root(2) = root(36) root(2) = root(36 x 2) = root(72).
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
+6 is the positive square root of 36.
The positive square root of 289 is 17.

The square root of a positive number results in a positive number. For example, the square root of 25 is 5. * * * * * Not true! There are two real square roots for every positive number: one positive and one negative. -5 is as much a square root of 25 as +5 is. However, the positive root is the principal root and so is often presented as the only root.
the principal root is the positive square root.
