Answer 1

There is a typo in the response options. The correct options should be:

a) √128
b) 8√2
c) 4√32
d) 16√2

To find the square root of 128, we can simplify it by factoring out the perfect square.

128 = 64 * 2

Taking the square root of both 64 and 2:

√64 * √2 = 8 * √2

Therefore, the square root of 128 is 8√2.
