Question

Hey:) can you please help me posted picture of question

Answer 1

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

Answer 2

Option B gives the correct answer.

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


`(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`
