Its the inside of the parenthisis. Ex: Square root sign ( any number of your choice)
If unspecified, the square root is the principal root, which is the positive root.
It is the principal square root.
Really ! To square a number represented by anything inside a square-root sign, take away the square-root sign. The square of [ sqrt(792) ] is 792 .
you buy a calculator and put the square root sign and the number you want to square root.
Get a calculator with the radical sign, press on whatever number you want to square root, and then press on the radical sign.
The radical symbol, otherwise known as the "square root sign", lets you take the nth root of any number.Any number can be placed above, and slightly to the left, of the square root sign, to indicate the nth root. For example, the cube root of 27 is 3.The number inside the square root sign (that which you are finding the square root of), is called the radicand.
Negative square root is -√Square root of negative one is i.
The square root of -6400 is not a real number because the square root of a negative number is not defined in the real number system.
The sign that is used for the square root is actually a root sign: the little 2 before it denotes that it is the square root. A little 3 would indicate it is a cube root, a little 4 that it is a fourth root and so on. However, conventionally, if no number is shown, it may be assumed that it is the square root.
simply see what you can multiply twice to get the number under the square root sign.
