It seems like you're trying to express an equation involving \( a^n \) and a conditional statement related to \( n \). However, the notation you've used, particularly the part "(n = 1) x 2", is a bit unclear.
If you mean that \( a^n = 5 \) when \( n = 1 \) (and perhaps there is a different relationship for other values of \( n \)), we can clarify this.
If \( n = 1 \): \[ a^1 = 5 \]
This implies: \[ a = 5 \]
For \( n = 2 \), if you meant to express that it has a different relationship, could you please specify that relationship? Otherwise, if you want to continue exploring \( a^n \) for different values of \( n \) or have another context in mind, please let me know!
