Answer 2

1. Resolva as divisões:

a) \frac{2x}{2x}

2x

------- = 1

2x

b) \frac{-8x^{2}}{4a})

- 8x²

------

4a

4(-2x²)

----------  elimina AMBOS (4))

4(a)

- 2x²

------ =  - 2x²/a

a

c) \frac{10x^{3}}{5x^{2}}

10x³

-------

5x²

5x²(2x)

------------  elimina AMBOS (5x²)

5x²

2x  ( resposta)

d) \frac{9n^{2}}{3n^{2}}  

9n²

-----

3n²

3n²(3)

----------- elimina AMBOS 3n²)

3n²
