Alguém me ajuda por favor ?

Answer 1

A) 2.1012 + 3. 1012 = 2024 + 3036 = 5060

B) 4.1013 -- 3.1013 = 4052 - 3039 = 1013

C) 5.10-12 + 3.10-12 = 50 - 12 + 30 - 12 = 80 - 24 = 56

D) 6,25. 10-34 + 2,75. 10-34 = 62,5 - 34 + 27,5 - 34 = 90 - 68 = 22

E) 8,2. 10-5 – 5.10-5 = 82 - 5 - 50 - 5 = 82 - 60 = 22

F) 3.1014 – 15.1012 = 3042 - 15180 = -12138

G) 0,00012 + 3.10-5 = 0,00012 + 30 - 5 = 0,00012 + 25 = 25,00012

H) 45000+5.105 = 45000 + 525 = 45525

I) 0,000052 + 10-5 = 0,000052 + 5 = 5,000052

J) 10-12 + 10-13 = 20 - 25 = -5

Bons estudos! :)
