No, Ellie is not correct.
Please assume that I am writing in terms of exponents:
The expression (a2)2. (a3)2 = (a)4.(a)6 [since 2. 2 = 4 and 3. 2 = 6]
= (a)(4+6) [since product of a term with different
exponents is equal to the term raised to the
power of the sum of the exponents]
=(a)10
Therefore the answer is n=10
