The following questions show the method to use to solve the above questions:

Part a)

i) $[\\frac{3^2.2^4}{3^{-2}.2^5}]^2$

$[\\frac{3^2}{3^{-2}}]^2.[\\frac{2^4}{2^5}]^2$

ii) $[\\frac{5^3.7^2}{5^{2}.7^4}]^{-1}$

$[5^1]^{-1}.[7^{-2}]^{-1} = 5^{-1}.7^2$

iii) $\\frac{24x^2.y^{-4}.z^3}{8x^3.y^7.z^{-3}}$

$\\frac{24}{8}.x^{2-3}.y^{-4-7}.z^{3+3} = 3.x^{-1}.y^{-11}.z^{6}$
