If 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.
Given the following functions, perform the indicated operation and state the domain.
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:)

i don't understand. Can you please explain in simplier terms, thanks:)
you can not take the square root of a negative number, so x may not be negative
there is no negative number though
There is no negative X in the domain, exactly. The domain is all POSITIVE real X
