Question

► Aritmética:
1. Sendo a = 10-1 e b= 10-2, calcule:
a) a +b;
b) a - b;
c) ✓b
d) a x b;​

Answer 1

Resposta:

a)17

b)1

c)2.828...

d)72

Answer 2

a= 10-¹ = 1/10 = 10/100

b= 10-² = 1/10² = 1/100

a) a +b = 10/100 + 1/100 = 11/100

b) a - b= 10/100 - 1/100 = 9/100

c) ✓b = √1/100 = 1/10

d) a x b = 1/10 × 1/100 = 1/1000
