# confusion with negative indices watch

1. If 2x^(3/2) can be written as 2x^3*x(1/2)

how can you write x^(-3/2)

I thought it could be:

x^(1/2) / x^3

or

x^3 / x^(1/2)

But thast wrong, cos substituting any value of x in, give two different answers. Any idea of the correct way of writing it? Its killing me!
2. Well with negative indices, it basically means x^-n = 1/x^n

So it's just 1/x^(3/2)
3. ahh right thanks
