Question

If p-1/p=2, find the value of p^3+1/p^3. ​Help me fast.

Answer 1

`\\\\(P^3 \ + \ 1)/(P^3) = 0`

Explanation:

Given;

`(P-1 )/(P) = 2\\\\From \ the \ equation \ above \ we \ determine \ the \ value \ of \ p \ as \ follows;\\\\P-1 = 2P\\\\P-2P = 1\\\\-P = 1\\\\P = -1`

`Now\ solving \ the \ given \ question;\\\\(P^3 \ + \ 1)/(P^3) \\\\Substitute \ the \ value \ of \`
