Simplify frac 16 81 frac 1 4 div frac 9 16 - fr... - JAMB Mathematics 2011 Question

((\frac{16}{81})^{\frac{1}{4}} \div (\frac{9}{16})^{-\frac{1}{2}})

((\frac{16}{81})^{\frac{1}{4}} \div (\frac{16}{9})^{\frac{1}{2}})

((\frac{2^4}{3^4})^{\frac{1}{4}} \div (\frac{4^2}{3^2})^{\frac{1}{2}})

(\frac{2^{4 \times \frac{1}{4}}}{3^{4 \times \frac{1}{4}}} \div \frac{4^{2 \times \frac{1}{2}}}{3^{2 \times \frac{1}{2}}})

(\frac{2}{3} \div \frac{4}{3})

(\frac{2}{3} \times \frac{3}{4})

(\frac{2}{4})

(\frac{1}{2})
