Answer 1

a) 729/4096 : 81/256 - (- 4/2 +1/2)^5 :(4/2 - 1/2)² + 9/16 =
729/4096 * 256/81 - (- 3/2)^5 : (3/2)² + 9/16 = 
9/16 - (- 243/32) * 4/9 + 9/16 = 
9/16 + 27/8 + 9/16 = 
9/16 + 54/16 + 9/16 = 
72/16 = 
4,5 sau 4 si 1/2
b) [1/2 * 3/2 - 1/9] : 19/8 - [41/20 - 7/4] - 36/25 = 
[3/4 - 1/9] * 8/19 - [41/20 -35/20] - 36/25 =
[27/36 - 4/36] * 8/19 - 6/20 - 36/25 = 
23/36 * 8/19 - 3/10 - 36/25 = 
23/9 * 2/19 - 3/10 - 36/25 = 
46/171 - 15/50 - 72/50 = 
46/171 - 87/50 = 
2300/8550 - 14877/8550 = 
12577/8550
