SUMMARY
The regular expression (a U b)*(a U e)b* U (a U b)*(b U e)a* can be simplified by analyzing the components of the expression. The expression represents the union of two sets of strings generated by the Kleene star applied to the union of 'a' and 'b', followed by optional empty strings. Both sets described by (a U b)*(a U e) and (a U b)*(b U e) are equivalent, as they both encompass all strings formed by 'a' and 'b' with optional trailing characters. This equivalence allows for a more concise representation of the original expression.
