Question

1. Ashley and Brandon have different methods for finding square roots.

Answer 1

Ashley's method is the exact definition of the square root, so it is correct.

Brandon's method is incorrect: dividing by 2 and taking the square root and completely different operations, and it would only work in this special case.

For example, the square root of 9 is 3, but 9/2=4.5.

Similarly, the square root of 16 is 4, but 16/2=8, and so on.

You can try any other couple, it will never work.
