Provide an appropriate response.Tell whether the statement is true or false. Explain.According to the quotient rule for radicals,
=
, where b ? 0.
What will be an ideal response?
False. The quotient rule for radicals also includes the stipulation that and
are both real numbers. If n is even and a (or b) is negative, then
(or
) is not real and the quotient rule for radicals does not apply.
