What is the following product? cube root of 16 x to the 7th power times cube root of 12 x to the 9th power

Combine the cube roots: ∛(16x⁷) · ∛(12x⁹) = ∛(192x¹⁶). Factor out perfect cubes: 192x¹⁶ = 64x¹⁵ · 3x, so the product is 4x⁵∛(3x). This matches choice A, 4x to the 5th power times the cube root of 3x.
