Answer 1

√36 : (2/3)-²
√36 : (3/2)²
√36 :(9/4)
6 . 4/9 
24/9 ( simplificando por 3)
8/3

b- (3/2)-¹+ 1/5.2/3
(2/3)¹ + 1/5.2/3
(2/3) +2/15 (mmc 3,15 é 15)
(10 +2 )15
12/15 (simplificando por 3)
4/5

c- 1/5+2/3-1/2 (mmc 5,2,3 é 30)
(6+20-15)/30
(26 -15)/30
11/30

d-3/2-1/3+(3/2)²
3/2-1/3+(9/4) (mmc 2,3,4 é 12)
(3-1+9)/12
(18 -4  +27)/12
(45-4)/12
41/12

(1/2.3/4)-(1/2:4/3
(1/2.3/4) - (1/2 .3/4)
3/8 - 3/8
0/8 = 0
