Answer 1

Olá...

a)

7/6 + 4/3 ⇒mmc = 6

7 + 8/6

15/6 ÷ 3

5/2

b)

9/2 - 5/4 ⇒mmc = 4

18 - 5/4

13/4

c)

1/7 + 3 ⇒mmc = 7

1 + 21/7

22/7

d)

5/12 + 5/6 - 3/4 ⇒ mmc =12

5 + 10 - 9/12

15 - 9/12

6/12 ÷ 6

1/2

e)

9/10 + 4/5 + 5/2 ⇒ mmc = 10

9 + 8 + 25/10

42/10 ÷ 2

21/5

f)

4/9 + 1 - 2/3 ⇒ mmc = 9

4 + 9 - 6/9

13 - 6/9

7/9

g)

(3/2)⁵

$\frac{3^5}{2^5}$

$\frac{243}{32}$

h) (7/9)²

$\frac{7^2}{9^2}$

$\frac{49}{81}$
