Q. If u=4u = 4, what is 16u\sqrt{16u}?\newline_____
  1. Plug in value of extit{u}: First, let's plug in the value of extit{u} into the expression. So we got extit{u} = 44, and we put it in extit{sqrt}(1616 extit{u}).\newlineCalculation: extit{sqrt}(1616 extit{*}44)
  2. Multiply to simplify: Now, we gotta multiply 1616 by 44 to simplify what's inside the square root.\newlineCalculation: 64\sqrt{64}
  3. Find the square root: Alright, the square root of 6464 is 88, so that's our answer.\newlineCalculation: 64=8\sqrt{64} = 8
