f(x) * g(x)

3X^1/2*6X^1/3. I got 18X^5/6. But without using a calculator how do i find the domain?????? Thanks:)

**Damon**, Tuesday, March 18, 2008 at 7:34pmIf x is negative, then x^(1/2) is imaginary. (by the way x to the one third has two complex roots for negative x)

That kind of restricts the whole deal to positive real x.
