x = 0,0333...
10x = 0,333...
10x = 3/9
90x = 3
x = 3/90
x = 1/30
√9 = 3
15/10 + 2/3 = 45/30 + 20/30 = 65/30 = 13/6
Portanto:
- 1/30 + 3 - [13/6]
= 1/30 + 3 - 13/6
= 1/30 + 90/30 - 65/30
= 91/30 - 65/30
= 26/30
= 13/15
10x = 0,333...
10x = 3/9
90x = 3
x = 3/90
x = 1/30
√9 = 3
15/10 + 2/3 = 45/30 + 20/30 = 65/30 = 13/6
Portanto:
- 1/30 + 3 - [13/6]
= 1/30 + 3 - 13/6
= 1/30 + 90/30 - 65/30
= 91/30 - 65/30
= 26/30
= 13/15
