problem: math induction 1+27+125... +(2n-1)^3=n^2(2n^2-1)
Please help!!
1+27+125... +(2n-1)^3=n^2(2n^2-1)
this can be expressed in the form :
1^3+3^3+5^3... (2n-1)^3, now you can write the sum of the cubical equation using the formula and conclude the result...
Addto both sides:
The right side becomes
And the proof is complete.
