Thank you so much, Damon.
To solve this problem, we need to use the given equation pq = 3 and substitute it into the expression p^3q^4 + p^4q^5. Let's break it down step by step:
First, substitute the value of pq in the expression: (3)^3(3)^4 + (3)^4(3)^5
Next, simplify the exponents: 3^3 = 27, 3^4 = 81, and 3^5 = 243. Substitute these values into the expression: 27(81) + 81(243)
Now, perform the multiplication: 2187 + 19683
Finally, add the two values together: 2187 + 19683 = 21870
So the value of p^3q^4 + p^4q^5 is 21,870.
However, none of the answer choices match the result obtained. Hence, none of the given options are correct.
