Multiple Choice

Multiply using the rule for the product of the sum and difference of two terms. Assume any variable exponents represent whole numbers.
- $$\left( 8 a ^ { n } - 13 b ^ { n } \right) \left( 8 a ^ { n } + 13 b ^ { n } \right)$$

• A) \(8 a ^ { 2 n } - 13 b ^ { 2 n }\)
• B) \(64 a ^ { 2 n } + 208 a ^ { n } b ^ { n } - 169 b ^ { 2 n }\)
• C) \(64 a ^ { n } - 169 b ^ { n }\)
• D) \(64 \mathrm { a } ^ { 2 \mathrm { n } } - 169 \mathrm {~b} ^ { 2 \mathrm { n } }\)
