\(3^2 =9 \)
So, \(x^x = (3^2)^9\)
\(= 3^{18}\)
Answer: E

Question:
If \(x = 3^2\), then what is the value of \(x^x\)?
Solution:
\(x = 3^2 = 9\)
=> \(x^x =9^9 = (3^2)^9 = 3^18\)
Answer E
Note: a^\((p^c)\) is not the same as \((a^p)^c\)
For example: 3^\((3^2) = 3^9\), which is not the same as \((3^3)^2 = 3^6\)
