Find the product. $\left( x ^ { 4 n } \right) \left( x ^ { 5 n } \right)$ Assume that the variables in the exponents represent positive integers; for example, $\left( x ^ { 2 n } \right) \left( x ^ { 4 n } \right) = x ^ { 2 n + 4 n } = x ^ { 6 n }$ .

• A) \(x ^ { 7 n }\)
• B) \(x ^ { 6 n }\)
• C) \(x ^ { 9 n }\)
• D) \(x ^ { 5 n }\)
