1. Explain how the

meaning of rational
exponents follows
from extending the
properties of
integer exponents
to those values,
allowing for a

radicals in terms of
rational exponents.
Example: We
define 51/3 to be
the cube root of 5
because we want
(51/3)3 = 5(1/3)3 to
hold, so (51/3)3
must equal 5.
