Answer 1

A) [(2/3:1/12+2):(1/10)2^-10 3^]+1/2
[(2/3:1/14):(1/10)2^-10 3^]+1/2
[(28/3):(1/10)2^-10 3^]+1/2
[(28/3):(1/5)-30]+1/2
[(28/3):(1/5-150/5)]+1/2
(28/3):(149/5)+1/2
28/3.5/149 +1/2
140/447 + 1/2
0,3131 + 0,5
0,8131

Answer 2

Resposta:

A) [(2/3:1/12+2):(1/10)2^-10 3^]+1/2

[(2/3:1/14):(1/10)2^-10 3^]+1/2

[(28/3):(1/10)2^-10 3^]+1/2

[(28/3):(1/5)-30]+1/2

[(28/3):(1/5-150/5)]+1/2

(28/3):(149/5)+1/2

28/3.5/149 +1/2

140/447 + 1/2

0,3131 + 0,5

0,8131
