Explicación paso a paso:
A)
(3/4)².(-2)³+(-1/2)¹
9 . (-8) - 1
---- ----
16 2
- 72 (:8) - 1 - 9 - 1 - 10
------- ----- = ------ ----- = ------- = - 5
16 (:8) 2 2 2 2
***************************************************
b)
(1/2)-²+(1/3)-¹
= (2)² + (3)¹
= 4 + 3
= 7
*************************************
c)
-2.(3/2)³+1¹-(-2)¹
- 2 . 27 + 1 - (- 2)
-----
8
- 54 + 1 + 2
-------
8
- 54 (:2) + 3 = - 27 + 3 - 27 + 12 - 15
------- ------ = ------------ = --------
8 (:2) 4 4 4
************************************
d)
{(-5/3)-¹ + (5/2)-¹}-¹
- 1
{ - 3 + 2 }
----- -----
5 5
- 1 1
[- 1 ] = - 5 = - 5
------
[ 5]
*****************************************
e)
{3-¹ - (-3)-¹}-¹
- 1
{ 1 - ( - 1 ) }
---- -----
{ 3 ( 3 )}
- 1 - 1
1 + 1 = 2 = 3
--- ---- ----- -----
3 3 3 2
