good, you got to the result you wanted.
The adding of .^ ./ is what I meant
Now you can throw in vectors, as long as same length, and obtain numeric results, better than working with symbolic variables.

I used y and B to make it easier to read:
num = 2*y*(r^((y-1)/y)-1)
den = (y-1)*(B^4 - r^(-2/y))
out = sqrt(num/den)

Probably, but they didn't tell us which values are vectors. Probably this is a good place to start reading:
