Answer 2

Answer:

994,011,992

Step-by-step explanation:

Given : (998)³

We can write this as :

→ (1000 - 2)³

Identity : (a - b)³ = a³ - b³ - 3ab(a - b) Here, a = 1000, b = 2

→ (1000)³ - (2)³ - 3(1000)(2)(1000 - 2)

→ 1000000000 - 8 - 6000(998)

→ 1000000000 - 8 - 5988000

→ 1000000000 - 5988008

→ 994,011,992
