The negative square root of a number is expressed as -√n or -n^½.
The question probably may refer to the square root of a negative number.
In mathematics there is an identity i² = -1 so that i = √-1
The square root of a negative number can be shown in several ways.
For Example : √-36 = √( -1 x 36) = √-1 x √36
The square root of 36 is ±6, and the square root of -1 is i.
The solution to √-36 is therefore ±6i.
The 'radical': √
The radical symbol ( âˆš ) followed by a line above what's in the radical, designates positive square root.
There are no explicit symbols. The non-negative square toot is called the principal square root.
A symbol to help people
The atomic number.
No negative number can have a real square root.In math and engineering, the symbol ' i ' is used to representthe square root of -1 .Then the square root of -19 can be written as 4.3589 i (rounded).
Negative square root is -√Square root of negative one is i.
The symbol you should be looking for is " √ ".
The mass number
It's a little hard to be sure what you mean by this question without seeing what you are looking at. I can think of two likely possibilities: 1. A number which is the same size as the square root symbol and written at the same level but located just in front of the symbol. This would just be a multiplier. 2. A smaller, superscripted number, possibly tucked into the angle at the front of the square root symbol. In this case, it isn't really a square root symbol anymore. It's a symbol for the root indicated by the superscriped number. For instance, if the superscripted number is a three and the number inside the root symbol is 8, this would represent the cube root of 8, or 2 (2x2x2=8).
the symbol scientists use to represent the atomic mass number is the letter U.
Because there is no "real" sqrt of a negative number, i is used as a symbol, eg sqrt -4 = 2i
Variable: A letter or symbol used to represent a number or quantities that vary
it is any letter or mathematical symbol that represent a number or a set of number
I think it's. A variable
It is called a variable
