A) 12^55 : 6^55 : 2^50 - 7^1 * 5^0 + 13^2

2^55 :2^50 - 7 * 1 + 13^2

2^5 - 7 + 169

32 - 7 + 169

25 + 169=194

B)

(2 * 5)^3 + 45^45 : 9^44 : 5^44 - 2000^0

10^3 + 9^45 : 9^44 * 5^45 : 5^44 - 1

1000 + 9^1 * 5^1 - 1

1000 + 9 * 5 - 1

1000 + 45 - 1

1045 - 1 = 1044

C) 15^38 : 5^38 - (3^19)^2

3^38 - 3^38 = 0

D) 30^n+3 : 10^n+3 - 3^n * 3^3

3^(n + 3) - 3^(n + 3) =0
