f(z) = sq. rt of z-1 / z+1 --- both numerator and denominator are inside the radical.
I can write it as (z-1)^1/2 over (z+1)^1/2, right? If I simplify it using derivative of a quotient. Should I simplify (z-1)^1/2 and (z+1)^1/2 as whole numbers and multiply them to other terms, including adding the exponents? The teach said I couldn't because the one-halves are actually square roots so I can't count them as exponents. Help?
