Which expression is equivalent to xy^2/9

This questiion is just a bit ambiguous. One wonders whether you meant

y^(2/9)

or

y^2

9

Could you clarify this, please?

Unfortunately, you haven't shared the possible answer choices, so there's nothing to compare to your xy^2/9. Please share those answer choices now and point out which of the 2 possible interpretations of y^2/9 is the one you want.

good luck on your studies! : )
