Which expression is equivalent to open paren 4 y squared close paren cubed times open paren 3 y squared close paren ?

Raise each factor inside the parentheses to the third power: (4y²)³ = 4³y⁶ = 64y⁶. Then multiply by 3y², giving 64 × 3 = 192 and y⁶ × y² = y⁸, so the equivalent expression is 192y⁸, choice B.
