Answer 1

0,6 x 1/3 + 4/5 + (0,333 . . . x 3) / (2 - 1,98) + 1² = 
= 6/10 x 1/3 + 4/5 + [ (3/9 x 3) / (2 - 198/100) ] + 1 = 
= 6/30 + 4/5 + [ (9/9) / (200/100 - 198/100) ]  + 1 = 
= 1/5 + 4/5 + [ 1 /(2/100) ] + 1 = 
= 5/5 + [ 1 x 100/2 ] + 1 = 
= 1 + 100/2 + 1 = 
= 1 + 50 + 1 = 
= 52

Resposta: letra b) 52

Answer 2

0,6 x 1/3 +4/5 + (0,333.. x 3)/(2 - 1,98) + 1²
6/10 x 1/3 + 4/5 + (3/9 x 3)/(2 - 1,98) + 1
6/30 + 4/5 + (1)/(0,02) + 1
1/5 + 4/5 + 1/(2/100) + 1
1 + 1x(100/2) + 1
1 + 50 + 1

Resposta: 52
