The expression (2x^5y)(4xy^-2) can be simplified by multiplying the coefficients and adding the exponents of the variables:

(2x^5y)(4xy^-2) = 2 * 4 * (x^5 * x^1) * (y^1 * y^-2) = 8x^6y^(-1+2) = 8x^6y^1

Therefore, the expression is equivalent to 8x^6y.

The correct answer is A. 8x^6y.

Apologies for the incorrect response. Let's go through the simplification again:

(2x^5y)(4xy^-2) = 2 * 4 * x^5 * x * y * y^-2
= 8x^(5+1) * y^(1-2)
= 8x^6 * y^(-1)
= 8x^6/y

Therefore, the expression is equivalent to (8x^6)/y.

The correct answer is B. (8x^6)/y.
