I'm assuming no one's helped you yet because the question is too confusing.
A) Is it \(\sqrt[3]{8x} \cdot \sqrt{16x^2}\)
B) Or is it \(\sqrt{8x} \cdot \sqrt{16x^2}\)
C) Or is it \(\sqrt[3]{8x} \cdot \sqrt[3]{16x^2}\)
D) Or is it \(\sqrt{8x} \cdot \sqrt[3]{16x^2}\)
E) Or is it neither?
A = \(\sqrt[3]{8} \cdot \sqrt[3]{x} \cdot \sqrt{16} \cdot \sqrt{x} = 2\sqrt[3]{x} \cdot 4x = \boxed{8x\sqrt[3]{x}}\)
B = \(\sqrt{4} \cdot \sqrt{2x} \cdot \sqrt{16} \cdot \sqrt{x^2} = \boxed{8x\sqrt{2x}}\)
C = \(\sqrt[3]{8} \cdot \sqrt[3]{x} \cdot \sqrt[3]{8} \cdot \sqrt[3]{2x^2} = \boxed{4x\sqrt[3]{3}}\)
D = \(\boxed{4\sqrt{2x} \cdot \sqrt[3]{2x^2}}\)
E = Well, I can't help you there, but next time make your question clearer
