On 7… once you get to a^2 -b^2 =16,

Wouldn’t that be 5 and 3?

5^2 -3^2 = 16
And 5-3=2.

problem 16 you are really confusing. It's is very simple: three cases, a=2, a=4 or a=16. For x =2 then b = 16, (16/4= 4 and 2*4=16) . For a=4 then b= 8 (8/4 = 2 and 4^2=16) and finally for a=16 then b=4 (4/4 =1 and 16^1 = 16). So b can be 16, 8 or 4
