Answer 1

To find the square root of 128, we can simplify the expression.

First, we can break 128 down into its prime factors:

\[
128 = 64 \times 2 = 8^2 \times 2
\]

Now, we can take the square root:

\[
\sqrt{128} = \sqrt{64 \times 2} = \sqrt{64} \times \sqrt{2} = 8\sqrt{2}
\]

So the correct response is:

**8√2**
