Question

evaluate (1002) cubic

Answer 1

${1002}^{3} \\ = (1000 + 2) {}^{3} \\ = 1000000000 + 8 + 3(1000 \times 2)(1000 + 2) \\ = 1000000008 + 6000000 + 12000 \\ = 1006012008$

Answer 2

Step-by-step explanation:

(1002)^3=(1000+2)^3

(1002)^3=(1000)^3+(2)^3+3×1000×2×(1000+2)

(1002)^3=1000000000+8+6000×1002

(1002)^3=1000000000+8+6012000=1006012008
