Let a and b be positive real numbers such that \(a^{\log_{2}16}=b^{\log_{3}9}\) and \((a/b)^{1/2}=3\).

Question Parts

( a )
Show that the condition \(a^{\log_{2}16}=b^{\log_{3}9}\) leads to the algebraic relation \(a^{2}=b\).
( b )
Using the relation \(a^{2}=b\) together with \((a/b)^{1/2}=3\), determine the numerical values of \(a\) and \(b\).
( c )
Evaluate the expression \(\sqrt{a}+\sqrt{b}\) and give your answer as a fraction in lowest terms.
