And its negative counterpart.
Yes. Every perfect square has two roots: one positive and one negative.
They all have square roots. Square root of 1 is 1 Square root of 4 is 2 Square root of 9 is 3
The perfect square roots are simply the counting numbers: 1, 2, 3, 4, and so on.The square root of 1 is 1, the square root of 4 is 2, the square root of 9 is 3, the square root of 16 is 4, and so on....See http://www.naturalnumbers.org/psquares.html
There are infinity square roots. Here is why. 1s square root is one, 4s is 2, and goes on forever. So, any whole number is a square root. My guess. I am only in middle school.
Algebraically if we have a number 'x^2' Then its square is (x^2)^2 = x^4 For the square root of x^2 = +/-x
The principal root is the positive square root.
That refers to the positive root, at least if you take the root of a positive number. For example, 25 has two square roots - two numbers which, when squared, give 25. The positive one (+5) is called the principal square root (or 2nd. root).
Restricting the discussion to real numbers for now. In this case, the square root is only defined for non-negative numbers; the principal square root of a positive number is the POSITIVE square root. For example, both +5 and -5 are square roots of 25, since both - when squared - give you 25. But the positive square root (+5) is called the principal square root, and if you write the square root symbol, that's the number usually meant.
A positive number has two square roots, that is, there are two solutions to an equation like x2 = 100. The "principal square root" refers to the positive solution.
They are called real numbers. Negative square roots must be complex numbers.
true
A positive number has two square roots, its principal (positive) root and its negative root. This is because a negative number multiplied by a negative number equals a positive number. In this instance, the square roots of 256 are 16 and -16.
False
The principal root of a number is the positive real square root of the number - if it exists. Since -25 is negative, it does not have a real square root. Its square roots are the imaginary numbers +/-5i where i is the [imaginary] square root of -1. i is neither positive nor negative and so neither +5i nor -5i is a principal root.
The numbers 1 and negative 1 (-1) are both square roots of positive 1.The square root of negative 1 is the "imaginary" number i.

This is because if you multiply two negative numbers you get positive.
