It is the principal square root.
Yes. For example, 3 is the [principal] square root of 9.
The square root of an even number can be an even number (if it is a perfect square), or an irrational number (if it is not).
Use a calculator (if you need) to find the principal square root. The second square root is the negative of the number.
The second root would be the negative of the principal root.
The principal square root of 9, the positive integer which is the square root of the number, is 3.
The principal square root is a positive number which, when multiplied by itself, gives the original number. The second square root is the negative of the principal square root. So, for example, starting with 144. The principal square root is 12 because 12*12 = 144 and the second square root is -12.
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.
The principal square root is the non-negative square root.
It is the principal square root.
If unspecified, the square root is the principal root, which is the positive root.
Yes. For example, 3 is the [principal] square root of 9.
The principal (square) root of 10 is an irrational real number which equals approximately 3.16227766.
The square root of an even number can be an even number (if it is a perfect square), or an irrational number (if it is not).
The opposite of a square root is the square of a number. For example, the principal square root of 81 is 9, while the square of 9 is 81.
Assuming you know that your number is a perfect square, the square root of an even number is even, and the square root of an odd number is odd.
Use a calculator (if you need) to find the principal square root. The second square root is the negative of the number.
