Answer 2

a) - 7² + (-7)² =
- 49 + 49 = 0
b) - 2³ - 30 + 1 =
- 8 - 30 + 1 =
- 38 + 1 = - 37
c)(-2/3)³ + 1 =
- 8/ 27 + 1 =
m.m.c= 27
- 8/27 + 27/27 = 19/27
d)- 5² + (-3)² - 10 =
- 25 + ( 9 ) - 10 =
- 25 - 1  = - 26
e)3² + 3-² =
9 + (1/3)² = 
9 + 1/9 =
m.m.c = 9
81/9 + 1/9 = 82/9
f)5° - (-1) - (-1/2)² =
  1 + 1 + 1/4 = 
m.m.c =4
4/4 +4/4 + 1/4 = 9/4
g)(1 - 1/2)^4  +  ( 1  +  1/2)-¹
(2/2 - 1/2)^4 +  (  2/2 + 1/2)-¹
(1/2)^4  +  (3/2)-¹
1/16  +  (2/3)¹ =
1/16 + 2/3 =
m.m.c=48
3/48 + 32/48 = 35/48
