=
Sum is rational because is rational
c. StartRoot 16 EndRoot + StartRoot 169 EndRoot
=
= 4+13=17
Sum is not rational
d. StartRoot 44 EndRoot + StartRoot 25 EndRoot
=
Sum is not rational
e. ModifyingAbove 43 with bar + StartRoot 49 EndRoot
Sum is rational because ModifyingAbove 43 with bar is rational
