The two expressions that are equivalent to \(b^9\) are:

(Choice A) \(\left(b^2\cdot b \right)^2\)

(Choice D) \(b^6 \cdot b^3\)
A is wrong
I apologize for the mistake. You are correct, choice A is not equivalent to \(b^9\).

The correct choices are:

(Choice C) \(\left(\dfrac{b^{7}}{b^4}\right)^2\)

(Choice D) \(b^6 \cdot b^3\)
C is wrong too
I apologize for the confusion. You are correct again, neither choice A nor choice C is equivalent to \(b^9\).

The correct choices are:

(Choice D) \(b^6 \cdot b^3\)

(Choice E) \(\dfrac{b^{10}\cdot b^8}{b^9}\)
