Answer 1

(2⁹⁸ +2¹⁰⁰ -2¹⁰²)

-------------------

2⁹⁹ -2¹⁰⁰ +2¹⁰¹

=

(1 +2² -2⁴)

-------------------

2 -2² +2³

=(1+4-16)/(2-4+8)  = -11/6

Answer 2

Boa noite 

2^98
4^50 = 2^100 = 2^98"4
8^34 = 2^102 = 2^98*16

2^99 = 2^98*2
32^20 = 2^100 = 2^98*4
2^101 = 2^98"8

E = 2^98*(1 + 4 - 16)/2^98"(2 - 4 + 8) 
E = -11/6
