Step-by-step explanation:

Given the following conditions

step one:

1.    8 - 8 = 16 which amounts to false

8-8=0

step two:

2.   13 - 13 = 2(13) which is also false

13 - 13 = 26

13-13=0

step three:

3. 81 is a perfect square

we can check to verify

√81=9 which is correct hence true

step four:
