#### Sqrt

Function: sqrt (<x>) The square root of <x>. It is represented internally by `<x>^(1/2)`. See also `rootscontract`.

`radexpand` if `true` will cause nth roots of factors of a product which are powers of n to be pulled outside of the radical, e.g. `sqrt(16*x^2)` will become `4*x` only if `radexpand` is `true`.

There are also some inexact matches for `sqrt`. Try `?? sqrt` to see them.

```(%o1)                                true
(%i2) ```
