Answer 1

a=10^3:{123+34:[(2×3^2)^2:18-2002^0×1^2003]}
a = 10^3:[123+34:(18^2:18 - 1 × 1)]
a = 10^3 : [123+34:(18 - 1)]
a = 10^3 : (123+34:17)
a = 1000 : (123+2)
a = 1000 : 125
a = 8

b = (3^2 + 2^3 + 2^3×5^3:10^2):3^3
b = (9 + 8 + 8 × 125:100):27
b = (17 + 1000:100) : 27
b = (17 + 10) : 27
b = 27 : 27
b = 1

c = [3^2003:(3^2)^1001+(5^3)^2:5^4] :2^2
c = (3^2003:3^2002 + 5^6:5^4) : 4
c = (3^1 + 5^2) : 4
c = (3 + 25) : 4
c = 28 : 4
c = 7

b + c = 1 + 7 = 8
a = 8
deci a = b + c
