Question

using identities evaluate the following (1001)^3​

Answer 1

Answer:

1003003001

Step-by-step explanation:

1001 = 1000 + 1

(1001)³ = (1000 +1)³

by using the identity,

(a+b)³ = a³ + b³ + 3ab(a+b)

where a = 1000, b = 1

(1000 +1)³ = 1000³ + 1³ + 3×1000×1(1000 + 1)

= 1000000000 + 1 + 3003000

= 1003003001

Therefore, (1000 +1)³ = 1003003001
