14.
x=(2⁹⁰⁰·2⁶⁰⁰·2+64⁴⁰⁰:2⁸⁹⁹)²+2³⁰⁰⁷
x=[2¹⁵⁰¹+(2⁶)⁴⁰⁰:2⁸⁹⁹]²+2³⁰⁰⁷
x=(2¹⁵⁰¹+2²⁴⁰⁰:2⁸⁹⁹)²+2³⁰⁰⁷
x=(2¹⁵⁰¹+2¹⁵⁰¹)²+2³⁰⁰⁷
x=(2¹⁵⁰¹·2)²+2³⁰⁰⁷
x=(2¹⁵⁰²)²+2³⁰⁰⁷
x=2³⁰⁰⁴+2³⁰⁰⁷
x=2³⁰⁰⁴(1+2³)
x=2³⁰⁰⁴·9-patrat,perfect

y=5·(3²⁰⁰²-3²⁰⁰¹-9¹⁰⁰⁰)
y=5·(3²⁰⁰²-3²⁰⁰¹-3²⁰⁰⁰)
y=5·3²⁰⁰⁰(3²-3-1)
y=5·3²⁰⁰⁰·5
y=5²·3²⁰⁰⁰-patrat,perfect

(4³¹+6·32¹²-5·16¹⁵):(8²¹-5·8²⁰)-1=
(2⁶²+6·2⁶⁰-5·2⁶⁰):[8²⁰(8-5)]-1=
[2⁶⁰(2²+6-5)]:(2⁶⁰·3)-1=
(2⁶⁰·5):(2⁶⁰·3)-1=
5:3-1=2/3
