The code \times is used in LaTeX to make the symbol ×. The square root symbol is written using the command \sqrt{expression} . The n-th root is written using the command \sqrt[n]{expression} .
Example: The cube root in LaTeX is obtained by the command \sqrt[3]{x}, which yields 3√x.
\sqrt - Used to create square root and other root symbol.
You can set the number of the equations yourself with \tag and this will keep your equation numbers other than the tagged value the same.
By convention, superscripts and subscripts in LaTeX are created using the characters ^ and _ respectively; for example, the exponents applied to x and y in the code fragment above.
FAQs on Square Root Formula
The square roots of numbers other than a perfect square are considered irrational numbers. The principal square root of any negative number, say -x is: √(-x)= i√x, where, i is the square root of -1.
√2 = 1.41421356237309504880168872420969807856967187537694…
For general use, its value is truncated and is used as 1.414 to make calculations easy. The fraction 99/70 is also sometimes used as the value of √2.
The square root of 10 is expressed as √10 in the radical form and as (10)½ or (10)0.5 in the exponent form. The square root of 10 rounded up to 10 decimal places is 3.1622776602. It is the positive solution of the equation x2 = 10.
The square root of 3 is represented as √3 or 31/2. The numerical value of root 3 is given as follows: √3 = 1.732050807568877293527446341505872366….. To make the calculation easier, the value of root 3 is truncated as 1.732.
The square root of 14 is symbolically expressed as √14. Thus, if we multiply the number 3.742 two times, we get the original value 14. Square Root of 14 in Decimal Form: 3.742.
The value of root 4 is equal to exactly 2. But the roots could be positive or negative or we can say there are always two roots for any given number. Hence, root 4 is equal to ±2 or +2 and -2 (positive 2 and negative 2). You can also find square root on a calculator.
Superscript in math mode
To use Superscript with a symbol or character in LaTeX, you need to use the ^ key on the keyboard. For example, if you want to print x², you have to use x^2 and you must write it in Math mode of LaTeX.
A LaTeX command begins with the command name, which consists of a \ followed by either (a) a string of letters or (b) a single non-letter. Arguments contained in square brackets [] are optional while arguments contained in braces {} are required.
To create a numbered list in LaTeX, you can use the \begin{enumerate} command along with the \item command. You can also create sub-levels of the numbered lists by adding a sub-command within the greater enumerate environment.
#LaTeXTip: remove equation numbering for separate lines by adding “\notag” before \\ in the align environment. Use \begin{align*} and \end{align*} to switch off numbering entirely.
Therefore, the value of root 5 is, √5 = 2.2360… You can find the value of the square root of all the non-perfect square number with the help of the long division method. This is the old method which gives the exact value of the root of numbers.
The value of root 5, when reduced to 5 decimal points, is √5 = 2.23606. It has a place with a large list of irrational algebraic numbers.
