2181.729 + 243.81.27/ 3^2.9^2.234 + 18.54.162.9 + 723.729
= 2181.729+243.3.81.9/9.81.234 + 18.54.2.81.9+723.729
= 2181.729 + 729.729/729.234 + 1944.729 + 723.729
= 729.(2181+729) / 729.( 234+1944+723)
= 729.2910/729.2901
= 2910/2901
= 970/967
\(\frac{2181.729+243.81.27}{3^2.9^2.234+18.54.162.9+723.729}\)
\(=\frac{2181.729+243.3.81.9}{9.81.243+18.54.2.81.9+723.729}\)
\(=\frac{2181.729+729.729}{729.234+1944.729+723.729}\)
\(=\frac{729.\left(2181+729\right)}{729.\left(234+1944+723\right)}\)
\(=\frac{729.2910}{729.2901}\)
\(=\frac{970}{967}\)
