Question

O valor correto da expressão numérica E=(10-²).(10³):(10-⁴)+(8.8-¹)+10-⁴ é:
(A)58,0001
(B)8,000001
(C)100001,0001
(D)8
(E)80

Answer 1

E=(10-²).(10³):(10-⁴)+(8.8-¹)+10-⁴ 
E=(10⁻²⁺³) : (10⁻⁴) + (8¹+⁽⁻¹⁾)+10⁻⁴
E= 10¹ : (10⁻⁴) + (8⁰) +10⁻⁴
E= (10¹⁻(⁻⁴) + 1 + 10⁻⁴
E= 10⁵ + 1 + 10⁻⁴ 
E= 100000 + 1 + 0,0001
E= 100001 + 0,0001
E= 100001,0001 <-- opção C

Answer 2

(10⁻²).(10³):(10⁻⁴) + (8.8⁻¹) + 10⁻⁴
(10¹):(10⁻⁴) + (8⁰) + 10⁻⁴
10⁵ + 1 +1/10⁴
100.000 + 1 + 1/10.000
100.001 + 0,0001
100.001,0001
