ધારો કે $\omega$ એ એકમનું કાલ્પનિક ઘનમૂળ છે. તો $2(\omega + 1)(\omega^2 + 1) + 3(2\omega + 1)(2\omega^2 + 1) + \dots + (n + 1)(n\omega + 1)(n\omega^2 + 1)$ નું મૂલ્ય શું છે?

  • A
    $[\frac{n(n + 1)}{2}]^2 + n$
  • B
    $[\frac{n(n + 1)}{2}]^2$
  • C
    $[\frac{n(n + 1)}{2}]^2 - n$
  • D
    આમાંથી કોઈ નહીં
