H = 3^2.4^4.2^32/11.2^13.(2^2)^11-(2^4)^9

   = 3^2.(2^2)^4.2^32/11.2^13.2^22-2^36

   = 3^2.2^8.2^32/11.2^35-2^36

   = 3^2.2^40/2^35.(11-2)

   = 9.2^40/2^35.9 = 2^5 = 32

\(I=\frac{5.4^{15}.9^9-4.3^{20}.8^9}{5.2^9.6^{19}-7.2^{29}.27^6}=\frac{5.2^{30}.3^{27}-2^2.3^{20}.2^{27}}{5.2^9.2^{19}.3^{19}-7.2^{29}.3^{18}}\)

\(=\frac{5.2^{30}.3^{27}-3^{30}.2^{29}}{5.2^{28}.3^{19}-7.2^{29}.3^{18}}\)
