Answer 1

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

First, we can express 128 as a product of perfect squares:

\[ 128 = 64 \times 2 \] Since the square root of 64 is 8, we can write:

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

Therefore, the square root of 128 is:

\[ 8\sqrt{2} \]

So the correct response is:

8 start root 2 end root.
