Q. If j=2j = 2, what is 8j\sqrt{8j}?\newline_____
  1. Plug in j value: First, let's plug in the value of jj into the expression. So, j=2j = 2 goes into 8j\sqrt{8j}.\newlineCalculation: 8×2\sqrt{8 \times 2}
  2. Simplify inside square root: Now, we multiply 88 by 22 to simplify inside the square root.\newlineCalculation: 16\sqrt{16}
  3. Find square root: Lastly, we find the square root of 1616, which is 44.\newlineCalculation: 16=4\sqrt{16} = 4
