Option B gives the correct answer.

The step by step solution using the FOIL method of multiplication is given below:

[tex](8 x^{5}+9)(8 x^{3}+9) \\ \\ =8 x^{5} (8 x^{3}+9) +9(8 x^{3}+9) \\ \\ =64 x^{8} +72 x^{5}+72 x^{3}+81 [/tex]

We have the following expression:
 (8x5 + 9) (8x3 + 9)
 Rewriting we have:
 64x ^ (5 + 3) + 72x ^ 5 + 72x ^ 3 + 81
 Rewriting we have:
 64x ^ 8 + 72x ^ 5 + 72x ^ 3 + 81
 Answer:
 The solution for this case is given by:
 64x ^ 8 + 72x ^ 5 + 72x ^ 3 + 81
