Answered by harshaalanwalker

Step-by-step explanation:

$(1000 + 2)^3 = (1000)^3 + 2^ 3 +(3 \times 1000 \times 2(1000 + 2)) \\ \\ \\ 1000000000 + 8 + 6012000 \\ \\ = 1006012008. \\ \\ \\ 2.(1000 - 1) ^3 \\ = 1000 ^3 - 1 ^3 - (3 \times 1000 \times 1(1000 - 1)) \\ \\ = 1000000000 + 1 - 2997000 \\ \\ = 99700301$
