To find the square root of 128, you can simplify it as follows:
√128 = √(64 x 2)
Since the square root of 64 is 8, and the square root of 2 cannot be simplified further, the answer is:
8√2
To find the square root of 128, we can follow these steps:
Step 1: Divide 128 by any perfect square that is a factor of 128. In this case, we can divide it by 64, which is a perfect square.
128 ÷ 64 = 2
Step 2: Take the square root of the perfect square quotient obtained in the previous step.
√2
Combining the two steps, the square root of 128 is 2√2.
Therefore, the correct response is 2√2.
