Final answer:
C. -48x?y3. The product of -8x^5y^2 and 6x^2y is -48x^7y^3.
Step-by-step explanation:
To find the product of -8x^5y^2 and 6x^2y, we need to multiply the coefficients and add the exponents of the variables.
The product of -8 and 6 is -48.
The product of x^5 and x^2 is x^(5+2) = x^7.
The product of y^2 and y is y^(2+1) = y^3.
Therefore, the product of -8x^5y^2 and 6x^2y is -48x^7y^3.
