\(t,=\dfrac{3^{64}\cdot7^{24}}{7^{23}\cdot9^{66}}=\dfrac{7}{3^2}=\dfrac{7}{9}\\ u,=\dfrac{5^3\cdot3^4\cdot2^5}{5^2\cdot3^3\cdot2^4}=5\cdot3\cdot2=30\\ v,=\dfrac{3^6\cdot2^{15}}{2^6\cdot3^6\cdot2^8}=2\)

\(\dfrac{3^{64}.49^{12}}{7^{23}.9^{33}}\)
\(=\dfrac{3^{64}.\left(7^2\right)^{12}}{7^{23}.\left(3^2\right)^{33}}\)
\(=\dfrac{3^{64}.7^{24}}{7^{23}.3^{66}}\)
\(=\dfrac{7}{9}\)
