... yours is better though, in that you don't make use of exec.
My use of it was superfluous.
Changing my solution, in light of yours:
#===
def makeroot(N):
try:
assert type(N)==type(1) and N>=0
except:
raise ValueError("0 <= N <= integer")
fname = "root" + str(N)
if N==0:
globals()[fname] = lambda x: pow(x, 0)
else:
globals()[fname] = lambda x: pow(x, float(1)/N)
for i in range(11):
makeroot(i)
#===
