If `U={2,3,5,7,9}` is the universal set and `A={3,7},B={2,5,7,9},` then find: `(AuuB)^'`

Explanation

To solve the problem, we need to find the complement of the union of sets A and B with respect to the universal set U.

### Step-by-Step Solution:

1. **Identify the Universal Set (U)**:
\[ U = \{2, 3, 5, 7, 9\} \]
