Question: How do I get evalf to evaluate when two values are returned?

Hello,

I solved an equation, and Maple returns two values.  Even though I said, assuming v1i>0, the solve command returnse this:

How do I get Maple to give me two numbers for this expression just like it did for v1i?

 

Thanks!
