[tex] \sqrt x = x^ {.5} [/tex] and [tex] \sqrt [.5] x = x^2 [/tex]
They are the same but i want to know why.

[tex](\sqrt x)^2 = (x^5)^2[/tex]
[tex]x = x^{10}[/tex] (notice at this point that x is either 0 or 1)

An exponent is a mathematical notation that represents the number of times a base number is multiplied by itself.
The square root of a number is the value that, when multiplied by itself, gives the original number. It is denoted by the symbol √ and is the inverse operation of squaring a number.
\sqrt x
mean?\sqrt x
represents the square root of a number x. It is the value that, when squared, gives x.
\sqrt x
and x^ {.5}
?The notation \sqrt x
is the standard way of representing the square root, while x^ {.5}
is the exponential notation for the square root.
\sqrt [.5] x
?\sqrt [.5] x
represents the reciprocal square root of x. It is the value that, when squared, gives the reciprocal of x.
