Answer 2

Answer:

a-1124864

b-997002999

Step-by-step explanation:

a-We write it as 100 + 4

Using (a+b)^3 = a^3 + b^3 + 3ab(a+b)

Let a be 100 and b be 4

= (100)^3 + (4)^3 + 3×100×4(100+4)

= 1000000 +64 + 1200(104)

= 1000000 + 64 + 124800

b-a = 1000 and b = 1

= (1000)^3 - (1)^3 - 3 × 1000 × 1(1000-1)

= 1000000000 - 1 - 2997000

=997002999

= 1124864
