[tex] {( \frac{1}{3}) }^{4} \times {9}^{4} = ( \frac{1}{3} \times 9)^{4} = 3^{4}[/tex]

[tex] {12}^{2} \div ( \frac{4}{5} )^{2} = {12}^{2} \times ( \frac{5}{4} )^{2} = (12 \times \frac{5}{4} )^{2} = 15^{2} [/tex]

[tex]5^{5} \times { ( - 2)}^{5} = (5 \times ( - 2))^{5} = ( - 10)^{5} [/tex]

[tex] {( - 8)}^{3} \div {( - 4)}^{3} = (( - 8) \div ( - 4))^{3} = 2^{3} [/tex]

[tex]a) \ (\frac{1}{3})^{4}\cdot9^{4} =(\frac{1}{3}\cdot9)^{4} = 3^{4} = 81\\\\b) \ 12^{2}:(\frac{4}{5})^{2} = (12\cdot\frac{5}{4})^{2} = (3\cdot5)^{2} = 15^{2} = 225\\\\c) \ 5^{5}\cdot(-2)^{5} = ((5\cdot(-2))^{5} = (-10)^{5}=100 \ 000\\\\d) \ (-8)^{3}:(-4)^{3} = (-8:(-4))^{3} = 2^{3} = 8[/tex]
