Answer 2

what would you get for 16d * 3?

Answer 3

48d

Answer 4

\(\bf 8\sqrt{16d}\cdot 2d\sqrt{3} \implies 8 \cdot 2d \sqrt{48d}\)

now let's us simplify 48
\(\bf 8\sqrt{16d}\cdot 2d\sqrt{3} \implies 8 \cdot 2d \sqrt{48d}\\\quad \\
48 = 2\cdot 2\cdot 2\cdot 2\cdot 3 \implies 2^2\cdot 2^2 \cdot 3 \implies (2^2)^2 \cdot 3\\ \quad \\ \quad \\
8 \cdot 2d \sqrt{48d} \implies 8 \cdot 2d \sqrt{(2^2)^2 \cdot 3}\)
