I know how to do this with a pencil and paper but how do I do it in autoit?

http://en.wikipedia.org/wiki/Radical_of_an_integer

for example

504 = 2^3 * 3^2 * 7

and Rad(504) = 2 * 3 * 7 = 42

thank you. With a few modifications to your code it now works great

my code

Func R($Rad)
    if isprime($rad) Then
        return $rad
    EndIf
    Local $ToMul, $Splitted
    Local $Start = 1
    If $Rad = 0 Then
        Return 0
    EndIf
    
    For $x = 2 To 11
        Do
            If Not IsFloat(Execute('$Rad / $x')) Then
                $Rad = Execute('$Rad / $x')
                If Not StringInStr($ToMul, $x) Then
                    $ToMul = $ToMul & $x
                EndIf
            EndIf
        Until IsFloat(Execute('$Rad / $x'))
    Next
    $Splitted = StringSplit($ToMul, '')

    For $i = 1 To UBound($Splitted) - 1
        $Start = Number($Start) * Number($Splitted[$i])
    Next
    Return $Start
EndFunc  ;==>Radical
func isprime($int)
    dim $np = True
    for $i = 2 to 9
        $d = $int / $i
        if $i <> $int and IsInt($d) Then
            $np = False
            ExitLoop
        EndIf
    Next
    return $np
EndFunc

this version should not has problem:

MsgBox(0, '', Radical(7))

Func Radical($Rad)
    Local $ToMul, $Splitted
    Local $Start = 1
    If $Rad = 0 Or 11 Or 13 Or 15 Or 17 Or 19 Then
            Return $Rad
    EndIf

    For $x = 2 To 19
        Do
            If Not IsFloat(Execute('$Rad / $x')) Then
                $Rad = Execute('$Rad / $x')
                If Not StringInStr($ToMul, $x) Then
                    $ToMul = $ToMul & $x
                EndIf
            EndIf
        Until IsFloat(Execute('$Rad / $x'))
    Next
    $Splitted = StringSplit($ToMul, '')

    For $i = 1 To UBound($Splitted) - 1
        $Start = Number($Start) * Number($Splitted[$i])
    Next
    Return $Start
EndFunc  ;==>Radical

i get 4 i shoudl get 2

and running my previous code for getting the radical of 39 instead of getting 39(3*13) as expected i get 3

your code doesn't work either

try MsgBox(0, '', radical(39)) expected 39(13*3) got 9

Hi,

here my solution to get radical:

Note: The algorithm based by Klaus Merkert, Hohenstaufen-Gymnasium Kaiserslautern, http://www.hsg-kl.de

Func _Radical($n)
    Local $F = ObjCreate("System.Collections.ArrayList")
    While Mod($n,2) == 0
        If Not $F.Contains(2) Then $F.add(2)
        $n = $n/2
    WEnd
    While Mod($n,3) == 0
        If Not $F.Contains(3) Then $F.add(3)
        $n = $n/3
    WEnd
    Local $t = 5
    Local $diff = 2
    While $t*$t <= $n
        While Mod($n,$t) == 0
            If Not $F.Contains($t) Then $F.add($t)
            $n = $n/$t
        WEnd
        $t = $t + $diff
        $diff = 6 - $diff
    WEnd
    If $n > 1 And Not $F.Contains($n) Then $F.add($n)
    Local $out = 1
    For $element In $F
        $out *= $element
    Next
    Return $out
EndFunc

; If someone need: a function to get prime factors
Func _GetPrimeFactors($n)
    Local $F = ObjCreate("System.Collections.ArrayList")
    While Mod($n,2) == 0
        $F.add(2)
        $n = $n/2
    WEnd
    While Mod($n,3) == 0
        $F.add(3)
        $n = $n/3
    WEnd
    Local $t = 5
    Local $diff = 2
    While $t*$t <= $n
        While Mod($n,$t) == 0
            $F.add($t)
            $n = $n/$t
        WEnd
        $t = $t + $diff
        $diff = 6 - $diff
    WEnd
    If $n > 1 Then $F.add($n)
    Local $out = ''
    For $element In $F
        $out &= $element & ','
    Next
    Return StringTrimRight($out, 1)
EndFunc

just use this :

$r=1/2 ; where 2 is ur radical power 

27^$r ; that is all .....

________

$variable^$variable2 

where $variable is ur number 

$variable2 is 1/ur_power

danyel,

Welcome to the AutoIt forums.

But in future please do not reply to 7 year old threads....

P.S. And certainly do not hijack them - start your own thread.
