PowerExpand

PowerExpand(expr)

expands out powers of the form (x^y)^z and (x*y)^z in expr.

Examples

>> PowerExpand((a ^ b) ^ c)
a^(b*c)

>> PowerExpand((a * b) ^ c)
a^c*b^c

>> PowerExpand(Log(x/y))
Log(x)-Log(y)

>> PowerExpand(Log(-13/350))
I*Pi-Log(2)-2*Log(5)-Log(7)+Log(13)
        

PowerExpand is not correct without certain assumptions:

>> PowerExpand((x ^ 2) ^ (1/2))
x
