1. The problem asks us to write the sentence "The product of -11 and -7 gives 77" as an equation. 2. "Product" means multiplication, so we multiply -11 and -7. 3. The multiplication of -11 and -7 is written as $$-11 \times -7$$ or simply $$-11(-7)$$. 4. Multiplying two negative numbers results in a positive number, so $$-11 \times -7 = 77$$. 5. Therefore, the correct equation is: $$-11(-7) = 77$$ 6. Among the given options, the correct one is: $$-11(-7) = 77$$
